Harrison looked much better , but it's hard to tell if that was result of new coaching or not. I have found that throughout his career he plays well on the big courts, for the big matches on the big days however...it's the in and outs, and finding a way to win when you are expected to beat another guy ranked 100 in world that is hard for Ryan because he relies to much on his athleticism and not enough of just playing good solid aggressive tennis.
I'm optimistic he'll have a decent HC season. I don't think though, from what I saw on Monday that the majority of his problems are solved. He still has that horrible slice backhand and just gets pounded on mercilessly by anyone who can draw that shot out of him. JMG needs to get that slice out his game or improve it so it's not so attackable.
