Hopefully this ends up being a good one. Was impressed with Jack at times last year, but I still think he needs to play more aggressively. Has a fairly big forehand when he goes for it, but he's really reluctant to do so in a lot of the matches I've seen. For whatever reason he prefers to just grind from baseline which I think limits him a bit. Match last year with PCB turned into a ridiculous grindfest.
Ultimately think it comes down how Nadal is playing. If he's able to play aggressively enough without making errors then I'm not sure what Draper will be able to do in rallies. If Nadal's groundies are lacking though, then this could turn into a physical match.
