This dude is a specimen, but is he really 6' 4' tall?
I know athletes' stats are regularly inflated for whatever reason, and it seems Bautista is doing the same. If you check out the link to the picture of the cast, you can see Vin Deisel who claims to be 5'11 3/4" tall (every little bit counts I guess) and he is almost as tall as Bautista. I don't think Bautista is over four inches taller.
