his vertical has got to be high no matter what his weight is
i asked a while back, brozknoz guy said it was measured at 30.
I think 30 is not all that bad for a guy that probably never jumps, but I would have expected a little higher VJ still. Shane Hamman for example has been reported to have had a VJ PR of 36", really good in and on itself, but also at a bodyweight of much over 300 lbs. He was also witnessed to do 5 back flips in the OTC right after a heavy single with 804 lbs...
