In terms of the rest of the group, you have Gronk who if you haven't been watching has a stake in the best TE argument. Brady has an unreal rating throwing in his direction it's like 135. He'd be good regardless of who is throwing him the ball.
Hernandez has first round type talent as well.
So yes I stand by my argument that Welker/Gronkowski/Hernandez> Bowe/Breaston/Baldwin. They might not be quite as dangerous vertically as the Chiefs group, but as a unit I'd take them 10 out of 10 times.
