Exactly the point. If you think he has this level talent and he is draftable for a small trade up (think they gave up a 4th) you have to look at what it might cost you to be in a position to get a guy you like this much most other years.
The Bills should do the same IMO. Once Josh hits 35 QB in round 1 should be on the table every year if a guy they really like slips to them in their traditional late round 1 draft spot.
