His ground positioning was really good but it looked to me like he was using his strength to put Heath into positions and keep him in positions
IMHO in a fight you use your main skills. one of Lesners MAIN skills is his STRENGTH. It is one of his 'principles' if you will. If you are as big as him .. .then you use it... if your not you use your other skills ... that is exactely the way it SHOULD be. It would be ridiculous for Lesner to not take advantage of his high level of power and strength.
Personally i believe 'strength' should be concidered a skill ... i mean it takes one hell of alot to achieve.
