It's been mentioned here pretty often that Jimmy Johnson's old trade value chart (pre hard salary cap, pre outlandish first round rookie salaries, pre rookie wage scale) was badly outdated and didn't really apply anymore, but this is the first I've seen of a replacement.

Looks reasonable to me, and also indicated that GB did pretty well on their trade with the Browns

#29: 202.61pts
first round premium: ~10
Packers total: 212

#33: 179.54
#97: 38.52
Browns total: 218

Pretty close!
