He was an undrafted free agent coming out of college. The Cowboys worked him out as a TE but cut him. The Chiefs grabbed him, and he has become possibly the best OL in the NFL. He was actually named the AFC offensive player of the week once last year as a G. That's never happened in NFL history. He's also the one who owned Ray Lewis in that MNF game last year when Lewis was miked up and crying like a ***** about being double-teamed on every play. As Madden pointed out, he was almost never double-teamed. Waters was owning him by himself.
