He's defintely better than a lot of guys out there, but he doesn't necessarily fit our system.
The best thing going forward would be an OC who uses a-based, spread-passing attack, deploying both quick throws from bunched sets, as well as deep throws. Can't be changing systems with Luck as the QB. Change like this is not good for a young QB.
Change has happened to the best QB's , the best QB's can pick things up do to hard work and practice, I think Luck would handle it well actually, Its not like he will have the same O Coordinator his whole career anyway, also the best O Coordinators will tie there QB's strength into there system(which Arians failed to do consistently) to make it an easier transition which in turn maximizes the chance for success both for the QB and the team, All my opinion of course
