It is perhaps worth noting that DeChambeau did not lead the field in driving distance in any of the four rounds, and was 7th overall, less than a yard ahead of Paul Casey. He does lead the Tour in driving distance for the year, but it seems, at least to me, a bit simplistic to attribute his win at Winged Foot to distance alone.
It is also worth noting that the win at the Open gave him a trifecta shared only with Nicklaus and Woods; the US Am, the NCAA individual, and now this. In other words, he has been winning at the highest level available to him before this, and to think that he only won at Winged Foot because of what he has done to his body and his swing speed in the last year seems, again, simplistic.
Unlike others that have posted so far, I don't like DeChambeau at all. I DO, however, find him, as well as his approach, fascinating; not just the added bulk and distance, but the equipment as well. I suspect that he is the first Tour pro EVER to have more loft on his putter than on his driver, and the single length irons have almost gotten lost in the shuffle.
But I'm not sure that what he is doing translates to other golfers very well, or that he can physically sustain this for an extended period. I am perfectly willing to be wrong, but I have trouble imagining his approach to his body being the wave of the future. We already know that, all other things equal, stronger is better, and I think the number of Tour pros who do NOT work out diligently has been in decline for years now. But doing what DeChambeau does? I just can't see it.
