5. Andrew Luck
If the Colts were 4-0 or 3-1, Luck may be higher on this list. But because they’re .500 with their only wins coming against the Jags and Titans, Luck is still without a signature victory to put on his MVP resume.
Luck leads all quarterbacks with 1,305 yards passing to go along with a league-best 13 touchdowns and four interceptions. His quarterback rating is fourth behind only Rivers, Manning, and Russell Wilson among starters.
The Colts are relying on the third-year signal-caller to be their difference-maker this year, as the talent around him is not meeting expectations. He has a tough stretch beginning Week 5 against Baltimore to get through, then we’ll see where he stands in the race.
