There are actually several QBs in the draft. Bradford will be out, Stafford, the QBs from Purdue, Clemson and Ball State are all highly regarded, Tebow might come out as might Sanchez, Cantwell from Louisville, Daniel, Harrell, JP Wilson, and honestly, don't forget about Bomar at Sam Houston.
I would say Colt would still be in the top 5, depending on what order you like, even if Bradford, Tebow and Sanchez all come out. Most people right now say the top 3 are Stafford, Bradford and Tebow in some order. I think Colt would be right around 3-5.
