Only biased haters can call Djokovic a pusher. And he is far from boring - he may actually be the most exciting player ever after Nadal.Even the most servebotting, slicebotting and errorboting version of Fed is still 10 times more interesting to watch than the most boring pusher of all time from - Novack Djokovic.
Let's be honest his style of serve and volley is really unexciting, nothing to do with the likes of Pete Sampras, Pat Rafter, Richard Krajicek, etc.Karlovic is the last serve and volley player around, also his backhand slice can be good to watch at times. This makes him more entertaining to watch than Isner or Opelka, although i quite like Opelka.
"Boring" is subjective. For example, watching Djokovic is very boring for me. It's really hard to get through his matches.
I'm Jealous you got to see Del Potro , but I can't imagine having to buy a ticket for Ivo Karlovic. Probably only on MTF would say , "Yes I am here to watch this QF 250 event to see Ivo Karlovic, should be a great match!!!"I really like Ivo Karlovic, but I once had to endure seeing him play Del Potro live in Stockholm. I like both of them so I was kinda hyped to see them. But Karlovic made it an absolute snoozefest. Its much nicer to watch him on tv where you can browse and keep half an eye on the live scores to come in and watch his tiebreaks.
It is possible that i would find Isner slightly more boring live, but he has slightly longer rallies
Seeing someone like del Potro play karlovic live felt like seeing one of the greatest dancers in the world dancing with Ivo Karlovic. With that said just before this match I got to watch Dimitrov vs Anderson live, which was a great match. When Dimitrov hits his slice on TV you dont get how good it is, live you can see how it floats with much more pace just centimeters over the net and the whole crowd just collectively sort of holds its breath, the way Dimitrov moves around the court is also very impressive live, and Anderson who normally is sort of boring to me is so impressive when he is ballbashing consistently, and moves into the net with his massive frame.I'm Jealous you got to see Del Potro , but I can't imagine having to buy a ticket for Ivo Karlovic. Probably only on MTF would say , "Yes I am here to watch this QF 250 event to see Ivo Karlovic, should be a great match!!!"
