If Borg couldnt even win the U.S Open from 75-77 on clay it is clear he wouldnt have ever won it those same years had it been played on hard courts instead. I laugh outloud at anyone who would even try and argue otherwise. The same goes for when he played it on grass in 73-74. The only reason he isnt 0 for 9 in winning hard court majors as opposed to 0 for 4 is the event was on other surfaces which actually greatly HELPED his chances to win the U.S Open, and he still failed.
