For you to think Rafa has a one dimensional game any more makes me realise your knowledge of tennis is seriously limited. Secondly how you get to Djokovic recovering being worse for Federer is quite beyond me. A dominant Djokovic will eventually stop Nadal in his tracks. He'll match Rafa on clay and along with Roger eliminate almost any chance Rafa has of winning slams off clay. It is unquestionably worse for Rafa than Roger if Novak regains his mojo, Federer simply has too many titles in the bank already anything accruing to Novak has to be worse for Rafa
I always find it funny when someone who doesn't know what they're talking about confronts my tennis knowledge. Usually when somebody does that they instantly regret it, you're not the first and probably won't be the last.
Yes, Nadull IS a one dimensional, glorified clay specialist who wouldn't have won more than 1 or 2 RGs in the 90s and earlier eras and have success anywhere close to what he has now but that is for another topic and another day. Even on clay, he needs the sun out, the clay to be dry, a tired opponent, ton of luck, be fresh himself, waste time between points and have every single advantage in the rallies from being a left hander(FH to BH being the obvious one) to get a clean win and he STILL cannot get a clean win. What a joke! Even today Faker should've won that first set and from there it's anybody's game.
As far as faker being a bigger threat to Fed than dull...were you in a coma in 2014-2016? I'm pretty sure faker did more damage to Fed than dull in that period aside from RG 15 where Nadull was simply not himself. If eggovic is giving fits to a well playing dull on slow clay even for a set, that means he's well on his way to recovery and winning bigger on faster tournaments, that includes grass and HC which is encroaching on Fed's territory. Fed hasn't beaten faker in a slam since Wimbledon 2012, let that sink in. Fed has grown a phobia of playing faker and that will come back to bite him if he plays him at Wimbledon and USO.
Ofcourse faker can beat dull like a drum and should be as he's the better player but it doesn't really harm him unless it's at RG. Sure USO has become dull's home away from RG due to the disgusting and scandalous court tampering and losing to faker there wouldn't be pleasant but it hardly hurts Nadull in the overall picture as he's already filled his quota of slams for the year at RG. However, if faker beats Fed at Wimbledon, then that could potentially derail Fed's entire season. By the time Wimbledon arrives, Faker would be in top flight form and could upset Fed there. USO will be even worse for Fed as faker will be much stronger there and Fed's form in 2018 has been shitty to say the least.
Until faker starts consistently beating Nadull at RG, not Rome, not Madrid, not MC, not USO, RG and RG only, he ain't damaging dull more than Fed.
