I think Andrew Luck is actually the more likely to suffer a sophomore slump than any of the other rookie quarterbacks. His accuracy was second worse in the league at 54.1% ahead of only Chad Henne. His 23 touchdowns were 14th. His 18 interceptions were third in the league (behind Brees and Romo who both threw 19). His 41 sacks were fourth in the league. His yards per attempt (7.0) is only good to tie for 18th.

Why bring up all these stats? If anything, Luck is likely to improve on most of these and thus avoid a sophomore slump, right? Here's the one stat that made everyone regard Andrew Luck as a superstar rather than a disappointment this season, though: the Colts were a staggering 9-1 in games decided by one score or fewer. Luck certainly had some phenomenal last-minute drives, but even the top quarterbacks in the league only win just more than half of one-score games. Aside from the Colts loss to the Jaguars, their other losses were bad. The next closest was losing by 12. I fully expect a regression to the mean for the Colts next season.
