Andrew Luck has come back strong from the shoulder injury that forced him to miss the entire 2017 NFL season. The Indianapolis Colts may be a disappointing 1-4, but that blame cannot be placed on Luck's shoulders. He has been impressive early on this season and has been one of the most productive signal callers in the league.

Throughout the first five games of the season, Luck has completed 66.5 percent of his pass attempts for 1,491 yards, 12 touchdowns, and five interceptions. He has also run for 53 yards on the season.

Fans in Indianapolis have been very vocal about their disappointment in the start to the season and some have even called for the Colts to trade Luck and start Jacoby Brissett. That would be a massive mistake and Luck's numbers show why those fans need to relax.

According to Frank Reich in a press conference shared by Pro Football Talk, there is concern in Indianapolis that Luck will not be able to sustain his pace throwing the football from early in the season. Reich isn't happy that he is having to make Luck pass as much as he has been.

“It’s killing me to have to throw this much. I know you can’t sustain this. The story doesn’t end well when you have to sustain this level of throwing. Maybe there’s exceptions to that.”

Luck has always been asked to handle a huge workload with the Colts. Chuck Pagano certainly relied on his franchise quarterback more than he probably should have.

At 29 years old, Luck is in his prime but surprisingly is already almost heading into the latter stages of his career. He has been banged up his whole career and it will be interesting to see how many more years he is capable of taking the beating he has taken while throwing as much as he has.

Indianapolis has one of the most talented quarterbacks that the NFL has seen in a long time. Unfortunately, ever since he was drafted No. 1 in the 2012 NFL Draft, they have found ways to waste his talent.

Reich needs to figure out how to support Luck more and keep him healthy. If he is able to do that, the Colts could find a way to have some big success over the next few years as their young talent develops.
