Here's the thing; it's really hard to get too much of a legitimate feel for a MLB'er until you know exactly what their responsibilities are each play and understand the combinations behind him (**** or MOFC etc.), so this isn't a complete condemnation of the young man.
That said, all I do is base my evaluations off of what I can see on the film. Not his star ratings, or what someone else says about the player- just what I can see.
The first thing that stands out is the lack of play strength that he plays with. He may have great workout numbers for all I know, but his play strength was quite weak. He did not stack and shed, in fact, he didn't really deliver legit strikes on his opponent, preferring to stop his feet and reach, lunge and grab. That's very poor technique and will get him annihilated against good competition. His speed is ok, not really Miami caliber speed. He's not big and I've already indicated he's not explosive strength-wise.
He seems to have good vision through trash and can find the football. Most of his highlights were eight yards down the field and on the backs of plays made by others. I didn't really see him make one impressive play in his entire film and I don't see the advanced athletic tools to develop into anything starter worthy. Quarterman was a far superior player and his tape is as a Junior in high school.
This one short tape is that of a low two star player who should be playing at the FCS level. Certainly not worthy of a Miami look based on what is on tape here.
Like I said, just how I see this.
