My buddy was also at his charity event that he has every spring in Tampa. My buddy's was specifically tasked with the job of getting Wade from the back of the room to the front of the room to give his address. He needed an escort to keep him moving. In the time it took to get from the back of the room to the front (maybe a 100 yds), Wade drank 8 beers. He would stop at a bar station, get drink two beers, and get two more for the walk to the next station.
He and another friend have also drank with Will Clark. Supposedly he's the same way with Coors Lights.
