I hate it when people are quick to jump to conclusions. It's a given fact that Luck struggles on the road. Everyone knows that. It's a confidence/mental issue now more than anything, especially being a rookie.
If this was his 3rd year and he was still struggling, I would be more on board with his comments. But it's completely unjustified to be making stupid regards like that to a rookie surrounded by mediocre talent, and a bottom 5 offensive line that's facing a top 5 defensive line.
Let's not forget Peyton's rookie numbers were what, like 18 TD's and 23 INT's?
