football not because he doesn’t still love the game https://www.coltsfanshop.com/Margus-Hunt-Jersey , but because it hurts too much to play it.Luck, who has been missing training camp and the preseason while rehabbing the latest in a long line of injuries, said in his retirement announcement that he doesn’t want to come to hate football because of the pain it causes him.“Over the past week I’ve been thinking, am I going to have a bunch of resentment toward this game? Or spite toward coming into this building? All I feel is love for this game and love for my teammates,” he said. “Physically it has taken its toll over the last four years, that’s why I’m here — and the mental and emotional toll as well.”For those who wonder whether the 29-year-old Luck might come back from retirement, that he still loves the game could fuel that speculation. But he sounds like he loves living a pain-free life even more, and he doubts he can ever do that if he keeps playing football. INDIANAPOLIS — The Indianapolis Colts spent their offseason cramming for Sunday’s test.They understood that to ascend in the AFC South, they needed a bigger, stronger offensive line, better coaching and different study habits. So far, they’ve aced it.Now they face their biggest challenge: Jacksonville’s daunting defense.“We don’t need any incentive. It’s the NFL, we go out there, it’s our job to protect the quarterback,” longtime left tackle Anthony Castonzo said. “The past is the past, we’re going to try the best we can.”Just about anything would be an upgrade over what’s happened lately against the Jaguars.When these teams previously met, late last season Peyton Manning Jersey , the Jaguars finished with four sacks — a significant improvement over the 10 sacks Indy allowed six weeks earlier last season.Those 14 sacks accounted for more than one-fourth of Indy’s season total, showing general manager Chris Ballard where the Colts needed to focus their attention to get back into the division race.Ballard found two starters in the draft, left guard Quenton Nelson in the first round and right tackle Braden Smith in the second. He added right guard Matt Slauson in free agency. Center Ryan Kelly returned to form following an injury-filled 2017 season, and even after Slauson went down with a back injury the Colts have managed to find solid replacements.As a result, Andrew Luck has been sacked just 10 times all season, none in his past 154 attempts — the longest stretch of his pro career.The improvement can’t be measured by pass protection alone. Marlon Mack rushed for career highs each of the past two weeks and has given Indy (3-5) its first back-to-back 100-yard rushing games since 2007.Still, the Colts know they are far from perfect and careful study of last year’s two game tapes reveal just how quickly Jacksonville’s defense can expose their lingering flaws.“I’m not going to tell you what our weaknesses are but this is going to be a big week coming off the bye,” Castonzo said. “It’s going to be tightening the screws on the things that we can.”But this Jacksonville team doesn’t resemble the one that reached last year’s AFC championship game, either.Despite being ranked No. 1 against the pass and No. 2 in total defense, only seven teams have fewer sacks than the Jags (19) and only three teams have produced fewer turnovers (seven).It explains why the Jags (3-5) have lost four straight and, like the Colts, are 2½ games behind division leader Houston.Coach Doug Marrone doesn’t expect this week’s challenge to get any easier, especially against an opponent hoping to ace its biggest test of the season.“It’s a really, really good group and honestly right now collectively, I would have to say when you look at them on film they’re probably the best offensive line that we have seen this year,” Marrone said.WELCOME BACKJaguars running back Leonard Fournette is expected to return after missing six of the past seven games because of a strained right hamstring.He practiced in full for the first time in more than a month Monday and did the same Wednesday. Marrone says the coaching staff won’t limit Fournette’s touches against the Colts.“We are full-boring everybody,” Marrone said. “Once a guy is ready to play Al Woods Color Rush Jersey , that has to be our expectation.”PAYING TRIBUTEAdam Vinatieri became the NFL’s career scoring leader at Oakland.On Sunday, the Colts will celebrate the record-breaking moment during a pregame ceremony at Lucas Oil Stadium. Details are being kept under wraps.Not surprisingly, the 45-year-old Vinatieri doesn’t want to make too big a deal out of it.“I want to keep it fairly low key,” Vinatieri said. “I don’t want to be a distraction. It’s a fun accomplishment, it’s a big accomplishment not only for me but for the guys I’ve played with. But at the end of the day the only thing I want to get out of this weekend is a win.”GOING BACKJaguars receiver Donte Moncrief, who spent the first four years of his career in Indianapolis, is looking forward to going back for the weekend.“There’s going to be a lot of emotions,” Moncrief said. “I’ve still got to go out there and play and make plays like I’ve been doing. Don’t try to make it too big. Just go out there and do what you usually do.”Moncrief has 29 receptions for 379 yards and two touchdowns this season. He signed a one-year, $9.6 million contract with the Jaguars in March, betting on himself to stay healthy and prove he’s worthy of a more lucrative, long-term deal in the league.MR. 3,000With seven passing attempts Sunday, Luck will hit No. 3,000.He needs one TD pass to tie Eli Manning (156) for the 10th-highest total in league history over a player’s first seven seasons and three to match Cam Newton (158) for No. 9.100<button class="view-gallery">View Gallery</button> Gallery:View from the sidelines: NFL cheerleaders 2018Raj Mehta-USA TODAY Sports | Raj Mehta
