What are you talking about no title? Hello...Go-Kart Champion in Vienna.
It may have not been a great season, but it was still a pretty decent season for him considering what he had been through the past year. He still has a long way to go before he can rightfully be back up in the top echelon, but he's making progress. No title this year, but 2 finals at least against two players who were playing at their best on the surfaces. If it hadn't been Nadal and Ivan in those finals, he probably would have walked away this year with at least 2 titles.
I do see a lot of parallels between his situation and Venus' (and not just because they're my two favorite players
). Similarly to Vee, I do think his game is still there, but there's some mental block preventing him from playing at his best. I think the same thing will need to happen to him as what happened to Venus in order for him to get back on track; there needs to be some devastating loss against a player he typically would beat to give him a wake up call (i.e., Venus' loss to Karatantcheva at Roland Garros).
