Indianapolis Colts T-Shirts , it’s time for your waiver wire approach to change.No longer are you stashing players for future impact. If you have a chance at the playoffs, you know your established starters. Unless injuries strike, you don’t want to take a player off of waivers and slide him right into your lineup.It’s also time to clear out guys you won’t ever start in favor of depth. If you are not going to use mediocre or unreliable players like Frank Gore or Michael Crabtree, cut them loose. What you need now is insurance at the all-important running back position. It’s the only position where your top player can suffer an injury and the backup becomes immediately relevant. You should be rostering the top NFL backups of your starting running backs if they are available. If your starting running back gets injured, you will not have to fight for his services on the waiver wire If you add him now.This approach, however, does not work at other positions. Backup NFL QBs are usually not the types you will want to start at all in fantasy, and the position is deep in one-QB leagues anyway. When a No. 1 NFL WR is injured, the No. 2 guy on the team is often already rostered if he is fantasy relevant. So focus on the preventative measures at RB for your playoff push.In some cases, such as New Orleans or the Chargers, two RBs are already useful and widely owned. Otherwise, here is a quick rundown of who you need to add or own as the handcuffs to your starting RBs if applicable. The backup to add is in parentheses. We list situations where the handcuff is clear, possibly unowned and the starter is usually or often a regular and important part of your lineup, even as a flex. Even if the backup is nowhere near as talented or productive as the current starter, an opportunity for adequate statistical output will be there if the starter gets injured.Rams: Todd Gurley (Malcolm Brown)Giants: Saquon Barkley (Wayne Gallman)Chiefs: Kareem Hunt (Spencer Ware)Cowboys: Ezekiel Elliott (Rod Smith)Panthers: Christian McCaffrey (Cameron Artis-Payne)Steelers: James Conner (Jaylen Samuels)Bengals: Joe Mixon (Giovani Bernard)Broncos: Phillip Lindsay (Royce Freeman)Patriots: James White/Sony Michel (Rex Burkhead)Cardinals: David Johnson (Chase Edmonds)Packers: Aaron Jones (Jamaal Williams)Texans: Lamar Miller (Alfred Blue)Seahawks: Chris Carson (Mike Davis)Redskins: Adrian Peterson (Kapri Bibbs)Falcons: Tevin Coleman (Ito Smith)Of course https://www.coltsfanshop.com/hats , that does not mean there are not any other adds to be made off waivers this week. There are indeed a few who have become relevant mostly because of injuries. Of the backup RBs listed above, Burkhead, who just came off injured reserve for New England, could fill in as either a runner if Sony Michel gets hurt again or as a receiver if James White goes down. Burkhead is only owned in 8.8 percent of leagues.Lions RB LeGarrette Blount (18.5) rushed for 88 yards and two TDs on Thanksgiving against the Bears defense, one of the best units against the run in the league. It is unclear when Kerryon Johnson may return from a knee injury and Blount has proven he is not quite done yet.Jaguars RB Carlos Hyde (38.8) could get significant work this week against the Colts with Leonard Fournette suspended for a week. In the same game, versatile Colts rookie RB Nyheim Hines (29.9) will be in line for quality duty if Marlon Mack is out with a concussion. He’ll be a respectable flex play in point-per-reception leagues.Tampa Bay WR Adam Humphries (28.2) is somehow being ignored in many leagues despite 26 catches and four touchdowns in his past five games. With some other WRs like Marques Valdes-Scantling and Golden Tate disappointing recently, Humphries can plug a hole if you need it.At tight end, Jonnu Smith (5.5) had a 61-yard TD reception on Monday night and has scored in three of his past four games. Jets rookie Chris Herndon (9.9) has double figure PPR totals in four of his past six games and is deserving of regular starting consideration. INDIANAPOLIS — Andrew Luck‘s health was Indianapolis‘ biggest question the past two years. But halfway through his comeback season, the star quarterback looks like his old self and the numbers suggest he’s actually playing better.Luck’s strong return has helped the Colts win back-to-back games for the first time in nearly two years, and they head into the bye weekend full of momentum and hope.“He made some incredible plays. I mean some incredible plays, conversions on third downs, plays that he shouldn’t make, plays that normal quarterbacks don’t make,” first-year coach Frank Reich said, describing Luck’s impressive game Sunday at Oakland.Many wondered if Luck could ever regain the form that had many calling him the league’s best young quarterback before Indy took him with the No. 1 overall draft pick in 2012.He exceeded the hype by leading the Colts to playoff appearances and earning Pro Bowl selections in each of his first three seasons.Then came the injuries and the losses. Luck hurt his right shoulder early in the 2015 season and wound up missing nine games — the last seven with a lacerated kidney. He sat out one game in 2016 with a concussion and missed the entire 2017 season after having surgery for a partially torn labrum in his throwing shoulder.But he’s answered the critics with a solid first half.Indy (3-5) needs one more win to match last season’s victory total and faces the second-easiest schedule over the second half. The Colts are two games out of the AFC South lead with five division games remaining and Luck getting even stronger.He is 225 of 342 with 2 Indianapolis Colts Hoodie ,187 yards, 23 touchdowns — a pace to set career highs in each category including completion rate (65.8 percent). He’s also flirting with the best rating of his career at 96.2. He had a 96.4 in 2016.Numbers tell only part of the tale, though.Luck has done it despite losing top receiver T.Y. Hilton for two games with a hamstring injury, Pro Bowl tight end Jack Doyle for five games with an injured hip and five different starting lineups on the offensive line.“You’re returning from an injury, you’re learning a new system, you’ve got T.Y. Hilton and some receivers hurt and you’re breaking in some new linemen — it’s not going to be as easy as people think,” Raiders coach Jon Gruden said before last weekend’s game. “I’ve got a lot of respect for what he has done in this league and what his capabilities are.”An improving cast could make Luck and Co. even tougher to contend with.From 2012-17, Colts running backs topped the 100-yard mark just four times. Last week, Marlon Mack became Indy’s first back with consecutive 100-yard games since Joseph Addai in 2007.The revamped offensive line has allowed just 10 sacks, a stark contrast to the 156 times Luck went down in his first 70 starts. In fact, Luck hasn’t been sacked in three games — the longest stretch since he left Stanford.Part of the explanation is Reich’s philosophical change, asking Luck to make quicker decisions.That, too, has showed in the numbers.His completion rate and rating against defenders within 1 yard of a receiver have jumped from 25.9 percent and a 45.0 rating in 2016 to 36.0 and 72.5 this season.And while his throws over 20 yards have declined from 2016 to 2018, his rating on throws between 11 and 20 yards has gone from 99.0 to 106.0.The one bugaboo continues to be interceptions. Luck has thrown eight this season Khari Willis Jersey , putting him on a pace to throw more than he has in all but two seasons. But five of them came in Weeks 5 and 6; he had none in the two games prior and none in the two games after.“No one on this team is going to go out with a sort of harness on them and say you can’t go play full speed,” Luck said recently. “I think our coaches do a great job of allowing us to play free and fast and loose, but within that, I guess at the same time you have to play disciplined.”Where would the Colts be if Luck had stayed healthy?Nobody knows.Yes, he would have reached 20,000 yards passing sooner. The Colts may not have missed the playoffs each of the past three seasons. His progression may have been a little steadier.But, for now, the Colts are just happy to have Luck back, playing well.“When you have the quarterback that we have, there is an expectation that we have to score points,” Reich said. “Everybody in this building knows we have an elite quarterback.”100<button class="view-gallery">View Gallery</button> Gallery:View from the sidelines: NFL cheerleaders 2018Raj Mehta-USA TODAY Sports | Raj Mehta
