After listening a bit of what Chris Sims had to say, (which IIRC was well before the draft and the combine) you have to wonder why the Panthers would simply give up on him after one season. Something here doesn't compute. On paper he seems like a perfect compliment to Bryce Young. They both come from basically the same offense and language. Both are RPO QB's. Both (according to Sims) are talented, decisive and smart. So what happened.
My fear is that Carolina is worried about Corral's chronic foot issues and cut bait. who knows the story on why he's out there.
Best Case Scenario- In about a month after Corral settles in he replaces Zappe as the #2 and BOB starts to develop the talent that Sims was raving about. Mac starts to excel like some of us expect and cements his place as starter. The Pats have a quality back up who is young and talented enough to keep him on his toes. Over the next 3 seasons, Corral gets a few starts and shows well and after his rookie contract is about to expire, he is traded for a 2nd day pick. OR becomes our #1 if Mac doesn't progress as we hope.
Worst case scenario - I have to listen to the "QB controversy" BS for the next 3 years.
