As to Becker/Nole combo, hard to pinpoint an angle at this point. I suppose time will tell. It's possible Nole wants to improve his serve and what better way to improve it than to hire one of the guys from the 90s. The game itself has become so physical these days with endless rallies that, it wouldn't surprise me if these players are looking for an easy way out to conserve more energies, but to their news, it's a hard weapon to have and even harder to develop at this stage. But let's see.
Andy in the meantime should hire Sampras so that he can improve his 2nd serve. lol
