While there was a lot of bad in Luck's debut, there was some good to take away from it.
Luck has little around him in Indy. He has an incompetent offensive line, a lack of talent at receiver and in the backfield, and a defense that provides little support. Despite that, Luck still threw for over 300 yards in his first NFL game.
Luck had nearly identical numbers in his debut to Peyton Manning's. In his NFL debut, against the Miami Dolphins, Manning was 21 of 37 for 302 yards, one touchdown and three interceptions. Luck was 22 of 43 for 309 yards, one touchdown, three interceptions.
Manning worked out pretty good for the Colts, and Luck will too. He is too good not to.
If the franchise continues to grow and put weapons around him, his potential is limitless.
