We're on the same page here. I've got Rich on my watch list but haven't been able to watch very much of him. My evaluation of him is incomplete right now, but I saw the same things you did in the TCU game. Very impressed.
Yeah, we need to watch more of him. Could be a sleeper here.
Also, in this game, Tejay Johnson was kinda undistinguished, so I don't have a pulse on him yet.
On the other hand, I watched 2 more games in which Antwine Perez (Maryland) played (against Navy and BC).
He caught my attention in the game against Clemson (while watching McDaniel) with some good plays, including a terrific pass break-up - an article will follow to describe it, even though I don't think it did quite the justice.)
I want to watch the Navy game because I'm thinking we can find out how he tackles in open space (agaisnt that triple option run game, there should be instances that the need arises - Sure enough, there were quite a few.)
Perez looks like a very good open-field tackler (in this game and also in the game against BC).
Against BC, he also displayed good hand and eye co-ordination along with good awareness to make the INT near the side line (he had 2 Ints in this game).
Overall, in the 3 games, it's often difficult to tell the difference between Perez and Kenny Tate (even though Tate is bigger, around 6'4-220, and is projected by NFLDraftScout to be the #1 FS in next year draft).
They played interchangeably (Tate is brought up near the LOS more while Perez actually played a little more as a FS) and worked well together.
They combined to stop a couple of wouldabeen TD run near the goal line (one resulted in a fumble that Perez recovered). He recovered another fumble in a short yardage situation in much the same fashion, showing great awareness for the ball (and again, hand/eye coordination).
I think he could be another sleeper.
But can he do it at the next level?
It's interesting to find out that he was a 5-star recruit out of HS and was offered scholarship by 47 schools.
I found this article that probably sums up the whole deal:
