On top of that (and I got this off a radio show so I don't have any links) there's word that Robert Griffin wants to start Law School and may return to Baylor and Landry Jones may be leaning towards returning to Oklahoma. Landry Jones' stock took a pretty big hit in my opinion towards the end of the season when he looked really average without Broyles.
In other words, in what could possibly be a very strong QB class could end up just being Andrew Luck and a then a bunch of 2nd-5th round talent. This could suck for the teams picking high that need and/or want a QB.
I think RGIII will probably end up coming out and, if Barkley and Jones both return to school, he'll be a top 5-10 pick. Going into the draft I would've ranked the "Big Four" 1.) Luck, 2.) Barkley, 3.) RGIII, 4.) Jones.
