yes there is overrating him. Do you think Demarcus Ware is a HOFer? I don't. Edge rushers are a new breed, All their value is in a sack. They don't contribute in the same comparison as a defensive end. And they tend to age out early because so much of their value is speed, when they lose a step they're no longer getting 15-20 sacks, they're closer to 10. Which has value, but isn't HOF caliber.
And Baalke isn't the best GM in the game. Ozzie Newsome, 2 rings many great teams, Ted Thompson, 1 ring, Aaron Rodgers, Jerry Reese, 2 rings, interesting one because the Giants ran so hot and cold, but hard to argue against the rings, and Bill Belichek are all for sure better. Of course you will be a homer and try to argue against it.
