The Indianapolis Colts of 2015 are among the biggest disappointments of the current NFL season. A team that was hyped up to be a force to reckon with, specifically on the offensive side, has spiraled into a complete mess. The seemingly talented offense led by the young, but gifted Andrew Luck has fallen to the bottom of league in various statistical categories in an extremely bizarre way, after putting on a show in the 2014 season as one of the league's top offenses.

The question is...why?

If anything, the offense is even more talented than it was in 2014 after adding Frank Gore and Andre Johnson. Johnson has been a disappointment thus far, but Gore has shown that he can still be a top running back in the NFL, something the Colts have not had in a very long time. Andrew Luck is coming off his best season in the NFL and only looked to be improving, so why has he been so bad in 2015?

The answer is offensive scheming and play-calling. The weakest aspect of the Colt's offense is the offensive line. It was not built to hold up for a deep passing attack. Teams are bringing pressure on these drop-backs and before Luck can even finish his steps, he has defenders in his face. Andrew has been far from perfect, making bone-headed decisions and forcing throws that should have never been made, but all the blame should not be put on him. In the second half of the Patriots game this year, while only down by one possession, Luck threw the ball 26 times in a row. Up to that point, Frank Gore was running the ball with an average of 6.0 YPC, which would've been even higher if not for a couple huge runs called back by offensive holding. There is no excuse as to why Gore wasn't utilized a lot more in the second half, and for majority of the other games this season.

Pep Hamilton has failed to make any sort of adjustment to utilize the talent on offense and hide the deficiencies of the offensive line. It's time to make a change and the sooner that happens, the better. Chuck Pagano is not a perfect head coach, and he does make questionable decisions at times, but he should have the ability to pick the coaches he wants so he can better coach the Colts. Rob Chudzinski may not be the answer long-term, but the current direction of the team will not get better unless a change is made.
