While Vince has done an outstanding job, how much have his athletes progressed since arriving ad what do the curves look like? He will tell you directly that he recruits well and then doesn’t do anything to screw his kids up.
Much of Dennis’ program is derived from Loren Seagrave. I think in the past his athletes have shown more improvement during their time with him, but that this was because many had more room to grow. As he has gotten more developed athletes, I’m not sure that this rings quite as true any longer.
As for the question regarding which programs have been influenced by the CFTS, I think that is very much a mystery for a myriad of reason.
