Paul Heyman is a genius and isn't given nearly enough credit for how much he impacted professional wrestling. We all say he's great for what he really did with ECW, but not enough of us really sit back and think about it. ECW influenced WWE's Attitude Era and because of that, they were able to defeat WCW. Furthermore, not only did it help WWE beat WCW, but the Attitude Era allowed WWE to launch itself and become the "entertainment phenomenon" that we know today. I put respect on his name for that.
Currently, I'm getting sick of his promos. They are feeling very repetitive, however, a lot of people still like them so I can't blame WWE or Paul for continuing with it. Don't fix it if it's not broken, brother.
And, of course, he's done wonders for Brock Lesnar, but even though Brock is a huge star and all, Paul's influence with ECW is far greater than what he's done with Brock.
