This is why so many of us look shocked with how our players do in the league, whether they're doing bad or good. Our evaluation skills suck apparently.
Two trends I'm noticing with the Miami guys in the pros.
1) They need to have at least one elite skill. That's why guys like Brandon Harris and Damien Berry didn't excel even though they were better college players than other former Canes. Those guys were pretty good at a lot of things but not great at anything. In the pros where are there no bad players, you need a difference-making ability or you're a dime a dozen. Sam Shields has elite speed, Orlando Franklin has elite power, etc.
2) They've got to be mentally tough. Tommy Streeter and DVD have the speed, but they get down on themselves easily and don't have the innate confidence of guys like Olivier Vernon or Brandon Meriweather. OV was getting in fights from Day One of camp and mentally pushed through periods where he was struggling. Most Miami kids are like that.
I talked to a couple football folks who went to Alabama after leaving Miami, and they told me flat-out that Miami had better talent at the top levels. They said that once these guys got to the pros and the other stuff (coaching, nutrition) became equal, their talent would shine through. The two examples they gave were Lamar Miller v. Trent Richardson and Olivier Vernon v. Courtney Upshaw. It sounded crazy at the time, but sure enough, the two Canes are outplaying the two Bammers.
