I wouldn't put Brown and the other guys you mentioned in the same micro-box as Welker. He's truly undersized and the rest of those guys are In the normal to optimum size for a WR, with Dez being exactly what you want in a do-it-all WR.

But I'm right there when it comes to the tall cats and that's a good point about the injuries. I tend to wonder how effective they would be if they weren't playing under these basketball rules of contact.
