I think both of them could beat Mark. Cole might be hard - but could be very competitive. This is an interesting matchup - 2hfh vs righty serve/lefty gs.Latest tennis troll match has two hard hitters who in the first set seemed to never go for net clearance. So this kinda 'coachy' rules about needing to do this or that are more like rules of thumb.. Could this yellow shirt guy beat Mark or Cole? I dunno.. I wouldn't bet against it. Dude's serve is pretty sick.. Guy also seems like super quick around the court..
