I think the BP number is a little overrated especially when you consider that running back from Utah put it up 29 times which makes him tied for fourth amongst the OL, but I still wouldn't want him on the line blocking for my QB. White had a very productive college career and given a proper [deleted] whupping coach, that 15 lbs will melt away.
He might have been beefing up for the pros and nursing that sore hammy. I suspect that most of the scouts were telling him to add some weight, just not THAT kind of weight.
