I think it should be obvious that a certain degree of length is needed to compete effectively on Tour. Someone who is a whizz with a hybrid is still going to have a tough time playing guys who hit short irons instead. But there probably comes a point of diminishing returns when the value of an extra 10 yards is outweighed by hitting more fairways. Course designers and those who set up the tournaments can influence the importance of these attributes. The US Open used to be an event where, most years, the course was tree lined with hideous rough, and if you missed the fairway by a foot, you had to hack out sideways. Likewise, around the greens, shin high rough, so missing the green even by a foot was bad news. So the winners were often plodding short or middle distance players who could hit a fairway with a 2 iron, then the green, sometimes with the same 2 iron. It wasn't very attractive to watch.
Bryson might win the odd event by a handful, but I think he will melt down just as often. The players in the top end of the OWGR are long hitters, DJ, Rahmbo, Rory, but they also all feature in the top 20 for total driving, so they have a decent amount of accuracy as well.
