A tangent .... but as regards the Avant catch:
The college football rulebook
as it stood in 2005 was completely agnostic about whether such was a catch. The rulebook never anticipated such a situation.
There were other games later in 2005 (Fresno State/Louisiana Tech) where a similar play occurred and the pass was ruled incomplete. As in the U-M/PSU game, the refs in that game ruled it as they did on-the-field. Because the rulebook provided no further clarification, it really couldn't be overruled.
The rulebook,
as it was amended in 2007 and still remains today --- it's definitely not a catch. See approved ruling 7-3-6-15 (page 181 of the link).
