Quite surprised at Kamke and Dodig qualifying.
Alcaide, Mahut, Fischer and Berankis could all be dangerous, Alcaide because of his serve mostly. The other 3 play well grass and are playing well.
Kamke had a pretty easy draw really. Levine sucks now and Tobias is in good form.
Dodig has a good serve and decent net/baseline ability, he's not great but he has a game that can play well on grass. Neither likely will win a match in the MD unless they play someone horrible on grass.
I agree about your dangerous guys, I really think Fischer could do some serious damage.
