Chris Harper
He was recruited to play QB for the Ducks. But, he injured his throwing shoulder before the season even started. So, because he's such a good athlete just running the ball, they found ways to get it to him from the slot.
We went through a brief controversy a couple months ago where people thought he was going to transfer because he was homesick and some Facebook comment (something like "I'm thinking about a lot.. a lot.") seemed to support that. But, then he said to reporters that it wasn't true. Most consider that episode to have been resolved. So, it would be a surprise if he did end up transferring.
Autzen has been sold out every game since 2002. Attendance is usually just over 60k (standing room tickets or something). They have said that there are plans to expand the stadium to add another 14-20k in capacity. But, no time-line as of now. Probably because they just started construction on what will be the most expensive ($200 million) basketball arena in the NCAA. Also, just re-instated Baseball, hired a top-class coach, built the diamond, etc. The anti-sports powers in the state are already fuming about those actions. So, they're probably going to wait on more football seats, for now.
That game was unbelievably loud. Almost too loud. It felt like it was making my eyes blurry somehow.
I think this gives a good feel for it (plus you can see some cheerleaders

):

I'm not sure. But, my impression is that they announced that they would not renew his offer
after Brown said he was going to official there. It might have been in reaction to Brown's announcement.
Seems like the Miami staff knows something we don't . Maybe they caught wind that he wanted to official with no intention of signing? In some cases, that's not bad publicity for a program. But, Miami has two stud RB's already and may want to just move on and show commitment to who they have.
If it's not something like that, I'd be surprised if they don't change course and extend the offer. So many fans and boosters there will be freaking out if they don't.
