Per Andrea Adelson, Mel Kiper says that he thinks Tim Tebow will go to the Bills at No. 41 overall, the 9th pick of the 2nd round.
As I have written here, I think that 41 is his floor -- more likely than not, the Bills will have to move up to get him. They should be nervous about the Browns picking 6th in the round, not to mention a team trading up with the Rams-Lions-Bucs-Chiefs. Not to mention Tebow going in the 1st round.
(Interesting to see Mel bend to the "reality" of mock drafts: Even the best draftnik needs to sublimate their opinion of the player's value for what will actually happen.)
