This is exceptional match. Murray' average offense level is much lower than this.No, just no. When Murray actually wanted to play offense he could do it better than Medvedev. Do you see how awkward Medvedev looks when he tries to actually go for his forehand? He practically has to throw his whole body into the shot, and this can't be consistent. Do you see how far back he plays on return? It's almost impossible to play offensive returns from that position. At best he's starting points in neutral. Murray also has much better court sense and recognizes when to play on or inside the baseline to attack. I personally have not really seen this from Medvedev yet.
Rewatch this and realize how ignorant your post is.
Even considering peak performance, Murray's shots has very less power/pace compared to Medvedev. Murray might be better taking ball early on return but Medvedev' overall offensive ground game is better. He has weapons - Murray never really had one. Outstanding performance in one match in your entire career doesn't prove anything.
