Huh, he's listed at 6'5" in one mag and 6'6" in another, and google listed 6'5" also.

I've seen the 6'7" listing on stuff from the WI Sports Information releases, of course, though SI groups usually inflate height, but according to nfl.com's combine info he is actually 6'7". He doesn't look that much taller than the other WI linemen, but then they're all big guys.
