Most of those guys seem like marginal prospects, except for Elijah Dukes. He's a superb athlete (top in TB's system according to BA) who broke out tremendously last year with a great effort. He's all or nothing though...extremely high risk/reward. He could become one of the top prospects in America next year, or you could never hear from him again.
Since the other guys are all rather limited, I'd go with Elijah Dukes.
