I do agree ball control is pretty good HOWEVER u have to take into account the pace of ball that is coming to them.. as far as i can see, ball speed is slow-medium.. if pace of ball is fast it's going to be much more difficult to re-direct the ball..
1) Not enough explosive movement and hitting
2) Lack of Pace.. infact i m going to say lack of trying to hit balls with pace.. Obvious reason ,fear of hitting it out which to me means lack of confidence..
Guy in black run around 80% of his BH and doesn't hit a heavy forehand.. i do believe both has adopt such a play when playing matches instead of trying to hit it bigger with more pace.. if you dun try and practice to hit bigger shots in matches for fear of losing there's no way your going to improve.. if i have to put a number to them i would say black shirt low 4.0 and high 3.5 for the guy in white WITH NO-LITTLE chance to up their ratings based on the way they play
