Keith Law of ESPN ranks Miller at #29 stating, "Miller is a potential No. 1 starter if he can keep his arm attached at all its various joints."
MiLB.com has Miller coming it at #10, apparently ignoring his long history of injuries.
The Good: When Miller is healthy and pitching, he remains awfully impressive. His low-to-mid 90s fastball can touch 98, and he backs it up with a low 90s sinker and plus slider. All three pitches can grade out above-average at times, and his changeup is solid. The Bad: The biggest concern for Miller at this point is his health. He should be in the big leagues by now, but he can't stay healthy enough to put the polishing touches on his game to get there. Despite a big frame and smooth mechanics, some wonder if he wouldn't be better off in the bullpen in order to preserve his availability.
