The biggest thing will be the coaching staff enforcing accountability with the players. Duval might have a bigger focus on speed and cardio-fitness than Phillip did, but that still has more to do with styles of play.
I agree with the accountability. You see this even at the HS level where some coaches tell you to lift, and they will, but how hard are they going? Some kids walk in there do bench, curls, look at themselves and go home. I think Phillip was a good motivator, but didn't know the science or stick to a program.
