His attorney can make any claims he wants about Collins' whereabouts, but if the authorities don't formally clear him of any involvement prior to the draft, I could see him not only falling to 50... but going undrafted. What team is going spend a draft pick on him if there's a chance he could be arrested for this in the near future? I'm not saying that because of wasting a pick, I'm talking about the publicity.
Collins is actually one of my favorite prospects... Either he gets picked where he was going to get picked, or he goes in between. There is no middle ground here.
