My guess is the appeals process has run itself out, and we are looking at the final decision.
Based on a lot of what has been posted, this is probably a he said / she said case. OSU has apparently decided to go with tie goes to the accuser, which may be a way for the administration to say OSU ≠ FSU, where tie clearly went to the defendant. On the one hand, it's sad to think that TG might be guilty of being a high profile athlete dealing with a vendetta. On the other hand, if the accuser went through the entire process, never changed her story and stuck with it despite having the knowledge of the football program breathing down her neck, that's an awful lot to go through for a vendetta. This is really all part of a bigger question of how to treat these kinds of cases, with things like Baylor, Stanford, etc coming up with increasing regularity.
