I think if you had said : Is Cilic less aggressive than in the past ?
the thread would have stayed more on the topic of Cilic ... and also would have looked truer as well.
I don't know why you made that title, but actually it was the best way to attract trolls and comments like that. Cilic's and Roddick's games and mentalities (and of course results) are so different. I don't think their evolutions are the same either : Cilic never had Roddick's serve and forehand then he was aggressive, yes, but not the same way the backhand and return are Cilic's best shots.
I think Cilic is a very interesting and peculiar player in himself ... but being peculiar, he's hard to understand for most MTFers.
I think there are in this forum people who are good enough technicians to analyse his game and I would be very interested in it, but I've seen that Leng Jai has been banned
