I knew about the attitude and am kind of surprised it's only coming out now. When he got injured, he immediately left the Bruins, declared, and pulled out of school. Seems like it's not a big deal; however, in and industry in which no stone is left unturned and mountains are often made out of molehills, does not reflect well on him.
That's not true, he waited until AFTER he had the surgery and then withdrew from school. That's why the rumor is that he was planning on trying to play again last year but after the surgery it became clear the knee was bad enough he should not play any more in college, just get to the NFL and start getting paid.
The attitude stuff was related to him and coaches and it was largely Jeff Ulbrich who didn't get along with anybody and was politely invited to find another job and leave, and he did.
Mora publicly stated he thought it was a mistake for Jack to leave he was taking a risk, but he was talking about NFL teams being scared of his knee, and he was right. He had a run in with the coaches at UW but there was good reason, during his recruitment Jack said he was told by coaches at UW if he went to UCLA he "would not do bleep in college and would regret it for the rest of his life." In fact Jack was so upset he asked the UCLA coaches to let him have the ball in every red zone possession against UW so he could show them how wrong they were.
The Panthers Gm seems to be agreeing with what I said the other day, the reason Jack is falling is he admitted right before the draft he's going to need microfracture surgery, and he even said if I play 4 years that's longer than the average NFL LB career. You can't say stuff like that when you're about to be drafted in the NFL, teams get scared by a kid being that honest.
The Cowboys have apparently come out and said they won't pick him with their 2nd rounder either they like him but are concerned about picking him that high.
This is all about his knee. I would add there's a guy on BRO who is saying NFL teams are actually doing Jack a favor. He fell out of the first round on concern about the knee, but now by passing on him, if he falls below 45, he gets the insurance policy which might turn out to be a huge deal for him financially.
