you said it well: SOLID, that's something Berdych and Tsonga are capable off in a good day but they aren't consistent enough to do it like Roger has been doing for the last 8 or 9 months.
Tsonga has a really good net game but he doesn't pick his moments well. He rushed the net at pretty idiotic times against Murray in the SF.
Berdych seems to only approach when he has an easy put away but I can't say for sure 'cause I don't watch his matches enough.
And I can't honestly remember a Wimbledon champion that has won by pushing, one way or another even defensive players like Rafa or Hewitt ended up being aggressive (at different moments) on the grass of the AELTC.
What about last year's? Genuinely asking.
I don't remember it very well.
