Luck will be fine long term from all the reports i've read, the Colts are in a full on rebuild anyway Ballard will improve the roster and won't take any chances on his shoulder that's why they're being super cautious it's about a career not this season, he knows they don't have a team good enough to risk Luck before he's 100% ready.
It's Chuck Pagano who's the big loser cause he's probably gonna miss 4 games and they're gonna be 0-4 and have another season without the playoffs and the GM will hire his own guy to complete his rebuild.
The risk is rushing him back before it's fully rehabbed and re-injuring it, the only person who would want that is Pagano to save his job but this decision is above his pay grade.
I still think Luck will win at least one Super Bowl in his career, he's 27 years old he's not even in his prime yet, everybody is down on Luck he was actually very good last year with a bad shoulder, it makes me laugh when he was playing very average people were acting like he was the greatest thing ever and last year when he was actually good but sunk by the roster people were down on him.
