Yes I do want the big 4 in the semis. Everyone is acting like a broken record 'i want new names' but whenever someone makes the SF(or even final like Ferrer did) they are routined by a big4 member.
If someone plays great, sure, but I don't want Berdych to beat Fed and then get smashed or Tsonga to take one out and then lose to Ferrer. Not to mention that I don't want Ferrer doing whatever the hell he does to get to Slam SFs and then getting blown to smithereens. Or what? Wawrinka beating Murray and getting destroyed by/choking to one of his masters? Haas getting tired half way? Isner/Raonic servboting one of them with 90% 1st serve in a borefest and then losing in another serveboting borefest?
I want good tennis in Slam SFs. And I don't want to know who will win the SF 2 days ahead.
Maybe Delpo can do something about it, but I'm not holding my breath on that.
Although I still do not want top 4 semis, you make a good point here. del Potro is the only other player that can be counted upon to raise his game once he gets to the SF stage as opposed to looking like a deer in the headlights - even if he does end up losing, he will make his opponent earn it (see Olympics last year, RG 2009, even WTF last year...). Ferrer's SF efforts vs top 4 are a huge joke, but that goes without saying, Tsonga tends to misfire dramatically after pulling one big win/upset and Berdych is Djokovic's and especially Nadal's turkey. So yeah, in terms of wanting uncertainty and tight matches I understand top 4 semis would be preferrable (or delPo, but he's rarely a factor these days due to his constant health problems).
