Ryan Van Bibber of SB Nation recently penned an article listing the BIG question for all 32 teams as they enter training camp. Here's what he wrote about the Colts:

Indianapolis Colts

Any worry about Andrew Luck's ability to fill Peyton Manning's shoes is nonsense. He has the head on his shoulders to match his talent, and probably understands that the Colts are not going to be contending for a Super Bowl anytime soon. He has a pair of rookie tight ends to work with and veteran Reggie Wayne in his corner. Just how far can he go in his rookie season?

Let's expand on this, shall we?

Andrew Luck's development is the biggest question. His soon-to-be consistently unfair comparisons with Peyton Manning will also be a hot topic of discussion. Throw in additional comparisons to Washington's Robert Griffin III and I'd argue that no quarterback has entered the league with more expectations and pressure to succeed than Andrew Luck.

There was a time when I'd argue that Manning had the most pressure on him to win. Ironic that it is now Luck who carries that weight.
