Nadal would have to win RG every year for the next five years to tie Roger's record. I find it hard to believe that within this time frame that either one or both of these scenarios happen.
A) Nadal begins to decline
B) One or more new star players will emerge that will challenge both Nadal and Djoker at the slams.
