I think Jon’s emphasis has been on execution of the “drive phase” rather than improving the speed of the 30m? hoping that tyson can reap the rewards further down the track? Is that not the theory behind the “drive phase”? I’m not sure how much tyson’s execution has changed though? But lets say tyson A can only “drive” for 20m and tyson B can drive for 35m but they are both running 3.80sec… would you not agree that tyson B is capable of running sub 3.80 if he got up tall and running at 20m? I don’t know if i’m making sense… it makes sense in my head??? :rolleyes: I would have to watch some clips of tyson and see whether his “drive phase” has improved since he started working with Jon. However I don’t think Usain at 6ft 5 should be beating tyson to 30m ??
