Seriously even Leinart may fall to the middle of the first round now.
I understand your point, that's a real longshot. Leinart is considered to be on the same plan of quality as Eli Manning was in his draft, and what Big Ben and Tom Brady are considered as young QBs in retrospect. The lowest he will go is #3. Frankly, the Titans, Jets, Raiders, Cardinals, and possibly Ravens and Dolphins all have a high enough need that they will draft the big 3. I doubt Young slips out the Top 10 with the Titans, Raiders, and Cardinals all poised to draft him. Cutler won't go higher than #7 to Oakland, but could feasibly slip to the middle of Round 1.
IMO, DeAngelo Williams would have been our pick had we kept the #15 pick.
