I hope the top 4 seeds make the SF's @ IW,but there could be some dangers along the way.Roger could face Raonic/Monfils/Potty,Murray could face Wawrinka/Isner or Fish,Isner & Fish won't be easy in the USA,Wawrinka Murray had some ups & downs with in the past.Djokovic has a good draw & the one danger early could be Anderson,i seem to recall he beat Djokovic once before.Nadal not playing Dubai should be fresh & he's got a great draw,Tsonga looks the Danger later.The draw on the hole Roger & Murray have the harder job to make the last 4 this time.
