Agree with @immamac that Quinn needs to clear out his team and start anew. Ron Slavin, his Southlake-based agent, has been certified by the NFLPA since 2004, but has only negotiated about 17 contracts in that time. Here are the ones I could find.
He makes reference to Miami and Notre Dame - and the timeline. Miami was likely tampering both Quinn and Carson Beck and might have said, "we'll get $4mm to the first one to sign." Notre Dame's QB room looks a little weak right now. That said, I wonder why no NFL teams were giving "if you are there in round N, we are taking you" advice to his agent. Or perhaps he was not getting the pre-draft feedback he needed.
Nothing he is saying at this point is helping Quinn. He needs to say things like, "Quinn is confident in his abilities and willing to do whatever it takes to excel at the NFL level. We believe Miami is a great place for that to start." And move on...
