Sorry but no. He wouldn't be able to make so many net approaches against a better player, and would make it much harder for him to win a point.
only reason the netplay was working so well was because he was playing very agressive. naturally any player is going to be stuck behind the baseline if he does this, even more competetant ones than Tomic. certainily other opponents will be tougher, but with the way Andy is returning then you have to imagine he could knock out some big guns. he's beaten all of the top guys before and can do it again if he's in form so it's bizarre that you would imply otherwise.
tonight he played smart, aggressive, and moved in at the right times. even against a better opponent he can do a lot of the same things, but time will tell.
