Yep ... count me in the "he's a quitter" group.
The only way I ever see Luck as anything but a quitter would be something along the lines of him announcing he was coming back and saying something along the lines of "I just needed a year to get right, now I'm ready ...etc .. etc ..."
You meant the 2015 season but that is a good thing IMO because he will finally retire hopefully . I just hope the Pats/Brady don't find a way to win it all like the Broncos/Peyton did. Pats do have a great defense like the Broncos had and Brady still has his smarts like Peyton did.
