It's very interesting to see what would happen to Fedal next year. To see what was left in their tank. I always believe their fate in tennis were intertwined together, though they are 5 years apart.
I think Federer would win 1 more slam in the next 2 years. As long as he can qualify to QF and SF regularly, he would continue playing and anything can happen from there. I think he can do this as the field before QF is still wide open for him.
Nadal's presence in slams would affect him in tricky way. He has good chance on all surfaces, but he couldn't just face what's thrown in front of him anymore. I think Federer is truly disappointed losing against Berd, because he comes here as the favorite and No. 1 player, so he wants to win a slam with that status, NOT as an "opportunist". But sadly, I'm afraid he has to be more like an "opportunist" if he wants to win a slam. I hope he can win just 1 more slam as No. 1 and the favorite, but it's more unlikely than being an opportunist, I guess.
This board is so reactionary. Don't see how anybody in the top 4 could be referred to as an opportunist. He sits at #1 and is a true contender at every slam. Berdych played really well, and Fed was off (especially the forehand) and still there was a chance. Things turned very quickly in that break game with the net cord. Just a bad day - that's why his still current QF streak in GS and his SF record are so awesome - that's a long time to win and not have injury, bad days, etc.
Fed will be fine - might not hold on to #1 but that's okay, he's got the record weeks at #1. Go home, rest up and enjoy your family for 6 weeks. Then come back strong for the indoor season. Still think he's the favorite at Wimbledon, but not the other GS as there are too many great HC players. Hope there's a new US Open champ - that'll be a long time there's been 4 different GS winners in a year. Interesting times.
