I respect Hewitt's ability to dig deep, and not throw it away when he's losing like so many other players.
However, apart from him being a dick, he's already won Wimbledon in the past, and I don't see what that did for Australian tennis back then? The flow on effect has obviously been very little.
Additionally, I don't believe in the rule that I must cheer him on because he is an Australian. I hate that line of thinking.
People forget Hewitt was the last person to win Wimbledon before Federer. I'd love someone new to win it, and I understand wanting Federer to not win it again, but not Lleyton.
Marat would be a dream, Rafa would be awesome, everyone else is pretty meh. Gasquet, Ancic, Baghdatis, Roddick and Haas would all be better than Hewitt.
That being said, I have noticed Hewitt being less of a prick on the court recently.
