I know not many on here follow College Football but from having the pleasure of seeing him play alot at Stanford it wasn't even debatable whether he was suited to playing in the NFL. Peyton Manning turned pro in 1998, Tom Brady in 2000. Luck could turn out to be the best QB since them and could go on and be better than them. His potential is huge, greater than those who have turned pro between 2000 and now, such as Aaron Rodgers, Eli Manning, etc.
Already he is 4th in the league in passing yards and level with Peyton for the most completions of over 20 yards. Those two stats tell the story. He is passing alot, taking chances, throwing deep and it's paying off because of his ability. His passer rating isn't great, his completion rate is average, but he is getting it done when he needs to with great passes at important moments.
Indy all of a sudden are becoming interesting. 5-3 and with Jacksonville, Tennessee and Buffalo to play in 3 of their next 5 (likely losing to NE and Detroit). If they can be at 8-5 going into the last few weeks they have a chance. They play Houston twice in the last 3 weeks, but better to play the class of the division late on when the QB is on fire and the team have something to play for than early on I reckon. If Indy make the play-offs Luck will have to stay at a high level, and if he does they have a chance and he also has a shot at making the AFC pro bowl squad in his rookie year.
