I think Mike is right that 'different' guys would be winning. It seems to me that as talented as today's players are, they are more skittish (not Scottish) and prone to collapsing at the slightest of condition changes. They don't seem to be as adaptable, and look for those perfect conditions of puting surfaces, or B&I performance to match their finery of skills. Once they get out of their perfectly honed rythms and routines due to outside influences of conditions of the playing surface, or interrelationship of weather conditions to maintenance meld of playing surfaces, they don't seem to have the adaptablility, generally speaking.
But, with time, and use of old equipment limitations, on the more inconsistent playing swards of FW and Green performances, the really great players would adapt rapidly with practice. The cream always comes to the top. But, just the way the head healers approach the psychological aspects of the game, and the pampered ambiance of todays modern course presentations, and all the attendent butt kissing the pros receive while in competition, probably would be a hinderance to them if they had to adapt to the overall conditions and atmosphere of the pro game back in the ODG era. IMHO....
