Federer's death has been greatly exagerated.
Three of his four losses this year have been against the very best, besides everybody goes through dry patches. Federer shows he can still play brilliant tennis at times. Lets not forget he is the defending Wimbledon champion, in my mind that makes him the favourite. One year of aging won't make much difference. Also Fed on grass (which is less demanding physically then slower courts) and with a day off between matches should be able to play at high consistent level. If not at Wimbledon he will win at the U.S open. I would not completely count him out of the French either (but he needs a great draw)
Fed for Wimby #8.
