I have a hard time evaluating long-term value with all these guys. I guess because it's a chicken vs. egg theory. Were they all 3 great because only one really was and the other 2 fed off him, or were they all 3 equally good and made each other better?
I tend to lean towards Cushing being the most athletic of the 3, Mathews having the most drive and highest motor, and Rey falling somewhere in between the other 2.
So after that extremely wishy-washy analysis, I'll stay on that path and say whichever of the 3 is chosen the latest will be the smartest pick, and all 3 will have equally solid long-term careers.
