Hold on, you have your trade wrong -- Brace was drafted the year before. Perhaps you meant Gronkowski? Plus Aaron Hernandez and Taylor Price were also drafted with the McCourty pick.
So let's start with McCourty, Gronkowski, Spikes, Price, Hernandez and the 2011 #17 for Suh.
In terms of "draft value," recall that in Gosselin's redraft he ranked 3 of those players #4, #19 and #30 overall in a verrry deep class. Since this is a hindsight draft, his retrospective rankings are a reasonable source of input for our value equation. So you've just traded the equivalent of #4, #19, #30, #61 and the following year's #17 for one of the best d-line prospects the league has ever seen.
Practically speaking, where does that leave your team?
Well, a defensive line of Suh, Wilfork and G. Warren would be phenomenal. But Gary Guyton would be your every-down ILB, Kyle Arrington and Darius Butler would be your starting CBs with a street FA at nickel, and Alge Crumpler would be your #1 option at tight end, backed up by street FAs. (Don't even think about filling holes with any vets making above minimum, this year or next, because you've just added $10 mil/year to your payroll. Suh's contract is closer to Brady's than Wilfork's.) And you don't have a lot of ammo to restock cheaply in the 2011 draft, either.
So on balance, I'm very happy as is. The 2010 draft was a rare bird, with deep enough talent to do a vast restocking of the roster. I wouldn't have wanted to sit it out, not even for Suh.
