from MMQB:
According to the chart, the third overall pick is worth 2,200 points. The value of the Pats' three top picks: 17 (950), 28 (660), 33 (580). Total value of the three picks: 2,190.
and this. same article:
Now, the chart is not gospel. Teams don't have to use it. But it just shows you how valuable the third overall pick is, and it's highly unlikely the Bills would take much of a discount, if any, for dealing that choice, particularly if it meant giving a division rival a franchise player for the next 10 years.
