I have to ask what is with the Karlovic hype? Anyone remembers when he beat any top 50 player the last time in a best of five match? Is there any other than the famous Hewitt win years ago? It will be a small miracle if makes it that far. Lots of more challenging opponents he could have drawn
It's not really "hype", it's just that the guy is so annoying. He can lose to anybody, but if he has a good serving day it might be impossible to win for anyone, especially on grass. Of course the best of five format puts him at a disadvantage in slams, but that doesn't change the fact that if he gets to the third round, we'll have a boring, nerve-wracking, tie-break filled crap of a match.
Also I don't think the return of serve is Jo's strong suit...
