So by this logic Rafa should also 'shorten things up'? Maybe he can hire Dr Ivo as a coach?
Nadal should always be looking to shorten things up. There's a reason he missed 7 months not that long ago. Obviously, there is a limit to how much he can realistically shorten things up, but I'd say he's been able to do it to an extent. He's never going to flat out shorten points on a rally to rally basis because that's not the kind of player he is, but in improving his serve, being more aggressive with his ground strokes, etc... he's done that. It was quite noticeable this summer. Obviously, this also depends on the opponent. Nadal just won't be hitting through someone like Novak with a 2-3 forehands and end the point routinely. There's a reason these guys push each other to 54 stroke rallies.
With that said, I don't think Nole added Becker for longevity's sake. Djokovic still moves as smooth s ever (whereas Nadal has actually slowed down throughout the years, despite being a top 2 mover), hasn't had a history of injuries, and like Nadal, there are limits to just how much he can shorten the points. He's more capable of doing it than Nadal to be honest, but there's a tradeoff. He risks being too aggressive, rushing his shots, and making too many errors. In fact, that's part of what held him back on occasions before his 2011 run.
I think Novak hired Becker simply because Vajda had to "step down."
