Also, drafting at #6, the four "cant miss" type players, Dorsey, C Long, J Long, and McFadden could all be gone by the time its NE's turn. According to the Draft Points chart, Dallas for instance, would have to trade both first rounders and a second to give the Pats equal value for the #6. I cant imagine that Dallas would do that for a shot at one of the second tier first rounders.
A Team in search of one of the three QBs, Chicage for instance would have to give up #10, a 3rd and 5th for the #6. Thats a a hefty price to pay to move up 4 spots.
