Considering Polamalu's amazing 2008-2009 season, and more recently, BJ Penn's dominance over Kenny Florian, should we give more credence to Marinovich's training system?

For those that don't know, Polamalu is probably the elder Marinovich's most famous trainee(?).  When he came to the Steelers, Polamalu was convinced, or maybe ordered, to participate in the Steelers' off-season training program. After a couple of injury-plagued seasons, he went back to train with Marinovich in the off-season before last season, and did so again this year, I believe.

Also, the Prodigy, MMA fighter BJ Penn, has always had conditioning issues, but looked in the best shape of his entire life in the most recent UFC big event, where he successfully defended his title.

I am pretty near convinced this unique training method is more effective than the traditional cardio plus heavy lifting programs most pro and college sports employ (in particular football).

What do you all think?
