Indianapolis Colts into position for one final , desperation heave Sunday at Philadelphia, he came out.With 5 seconds left and Indy at its 46-yard line, coach Frank Reich put in Jacoby Brissett.In some respects, the move made perfect sense. Brissett had the stronger arm, and given the slim chance of winning the game on such a play, it didnt make sense to risk everything with someone returning from major shoulder surgery.Soon, the questions started popping up, too, and Luck attempted to put them to rest.I know Im at a level where I can make all the throws and I feel confident that Im going out there with my full arsenal, Luck said Wednesday. I dont think anything is holding me back. But again, you can always get better, and I dont think Im anywhere near scratching the surface of realizing my full potential.Clearly, this has not been the same Luck who started his career with three straight Pro Bowl appearances.His completion percentage (68.5) through three games would be a career best. His yardage and touchdowns are down slightly J'Marcus Webb Jersey , while his interception rate continues to hover at about the same pace. Hes been more efficient on third downs and maybe slightly less efficient in the red zone.All of those traits showed up in Sundays loss at Super Bowl champion Philadelphia, where Luck went 25 of 40 and wound up with 164 yards more than half of those yards coming on the final two series with Luck attempting to rally the Colts from a 20-16 deficit.Luck has thrown for fewer than 200 yards 15 times in 73 career starts, though its only the fifth time hes failed to top 200 yards in consecutive games.Many wonder whether the changes are a result of Reichs offensive philosophy, limitations on Luck, a series of injuries to Indys receiving corps and offensive line, a function of still getting acclimated to this new offense, or some combination thereof.I feel free to call anything, he said. Theres no doubt there are times when youre going on the road and youre in a hostile environment, you might try to get it out early. But you cant stay in that mode. You cant play scared.The Colts (1-2) insist theyre not playing it safe and point to downfield throws that have been made just not always converted including a 33-yard pass interference penalty on the Eagles that set up Indys only touchdown at Philly.Playing two of three road games hasnt helped, nor has facing three solid pass-rushing teams with J.J. Watt, Jadeveon Clowney and winless Houston on deck.Indy could again be missing left tackle Anthony Castonzo, who has yet to play because of an injured hamstring; Pro Bowl tight end Jack Doyle, who missed last weeks game with a hip injury and is one of Lucks favorite targets; and likely right tackle Joe Haeg Jordan Wilkins Color Rush Jersey , who is expected to miss a couple of weeks after leaving last weeks game with an injured left ankle.Even Luck showed up on Wednesdays injury report with a sore groin. But it didnt keep him out of practice.None of it has changed Indys approach.We definitely want more chunk (plays) and we want to be able to we do take what the defense gives us, offensive coordinator Nick Sirianni said. If they are taking away our initial read and we want to push the ball down the field, we want to play smart football.Naturally, it was expected Luck would need some time to shake off the rust after missing 26 games over the previous three seasons. But if he and his receivers hooked up on a couple more plays, perhaps he wouldnt have to answer any questions.Honestly, I dont know if theres scrutiny or not, he said. But I think we, as an offensive unit, we put a lot of pressure on ourselves to do well, and certainly in the last game we did not do well. The red zone sticks out in my mind more than anything.NOTES: Running back Marlon Mack (hamstring) and defensive lineman Denico Autry (ankle) did limited work at Wednesdays practice. Defensive linemen Tarell Basham (personal reason) and Hassan Ridgeway (calf) did not practice. Also sitting out were Castonzo, Doyle and Haeg, tight end Eric Ebron (shoulder and knee), safeties Malik Hooker (hip and groin) and Clayton Geathers (knee) , and cornerback Quincy Wilson (concussion).100<button class="view-gallery">View Gallery</button> Gallery:View from the sidelines: NFL cheerleaders 2018Raj Mehta-USA TODAY Sports | Raj Mehta Eight NFL teams are looking for head coaches right now and theyll all profess great excitement about how their choices are everything they ever wanted at press conferences, but its worth remembering that a backup option wound up being one of the best hires off of last years coaching carousel.Frank Reich was the Colts plan B after Josh McDaniels decided to return to the Patriots at the 11th hour and hell be coaching the team in Kansas City next weekend after beating the Texans 21-7 on Saturday afternoon. That win was the Colts 10th since starting the year with a 1-5 record and wide receiver T.Y. Hilton explained after the game why the team bought Reichs message that the year wasnt over at that point.He played the game, and he has a way of communicating with players that lets you know he cares about you, Hilton said, via So everythings about the players, and when he talks about everybody coming together for each other, its easy to all rally around that.After Reich was hired last February, Colts owner Jim Irsay gave one of those press conference pronouncements about how perfect the fit was with Reich. It sounded like a bit much at the time, but it was much easier to believe Saturdays pronouncement that Reich should have been our first choice all along.
