Re: What is happening to Marin Cilic?
I think he is a very good player, but lacks that something extra that will take him further. Big forehand, but there are much bigger ones, and he can go way off on that side. Solid backhand, but much like del Potro/Soderling/Berdych. Moves well for a big guy, but movement can be exploited. Doesn't serve as big as he should, not much variety. You see him and think, ok, he's a complete package, but delPo, Soderling, Berdych seem like if they catch fire, they'll burn much more fiercely than Cilic.
He is entering the phase where he should start to become a consistent QF-SF presence, if he wants to make a push at the top.
