It might help if you set criteria for what "BEST" might be. It also may be true that - as in real life- the best changes, is fluid- in the shorter term. Think Rory McIlroy or Tiger Woods. Even these guys look bad any given week against the constant new crops of 'young guns'.
It might be easier to say "who would you say belongs on the list of the truly elite players currently active" as well as a "hall of fame" for all time greats from the past.
In the 'current' roster you would have to include names like Dansamcan, Bollox, Sebicu (RG king), and a few others who are in that league- but you could also have categories for "best putter" (statistically-% 1 putts, putts per hole), best from tee to green (avg distance, % fairways and greens), best "ham n egger" (% sand saves/rough).
It would be interesting if WGT had a statistical "best" list in the above categories, plus "most tournaments won", "most top 10's" "scoring avg. last 100 ranked rounds", and the like.
