DeFranco, Cressey, and Robertson?

What is the difference really between programs by DeFranco, Cressey, and Robertson? From what I can tell they all advocate lifting to get strong as hell, speed, and plyos. Is one really better than the other when it comes to training athletes, specifically football players?

I wouldn’t point a finger and say one is better, but DeFranco seems to train more football players and has more accessable info on his training methods for them online.
