yea I wonder about him also - just sure what to think about him
Can get confused by complex formations where multiple receivers are lined up on the same side and
Needs Improvement: Has a slight body frame and isn’t a powerful hitter. Strength is only adequate at the point of attack and can’t always make the tackle one-on-one on an island. Won’t be much of a threat close to the line of scrimmage at the next level; lacks the strength to consistently set the edge in contain or avoid getting washed out of the play by lineman in run support.
Doesn’t always feel the run play developing in front of him and will allow ball carrier to get on top of him before he reacts; instincts and anticipation are questionable at times. Tackling technique is off/on as are his pursuit angles

Weaknesses
Breaking Down When Tackling
This is without a doubt Moore’s biggest weakness when watching him on film, in my opinion. When running backs get through the hole and into the secondary, he does not do a good job of breaking down and wrapping up the runner. Often times he leaves his feet and tries to throw himself at the back’s upper body, only slowing him down for a split second. I would like to see him show better form when tackling and being aggressive when coming up to make the tackle, not waiting for the running back to make contact with him.
Disengaging from Wide Receiver Blocks
Often times on big run plays by the offense, I saw Moore not being able to get off of receivers’ blocks downfield. While he sometimes did a good job of moving the receiver to force the running back to cut a certain direction, he needs to be able to shed those blocks and make the tackle in order to be a good NFL safety. The ability to shed blocks as a safety and make the play can sometimes save a defense from giving up huge gains and even touchdowns.
One-Dimensional
After reading the previous strengths and weaknesses of my scouting report, you can probably draw the conclusion that I am high on Moore’s ability to play the pass but believes he needs to improve a lot when helping in run support. Teams who need help in pass coverage will have Moore higher up on their draft boards than teams who are looking for an aggressive safety that can effectively play in the box. The team that selects Moore approximately a month from now will likely not have him down near the line of scrimmage (besides short-yardage plays) but playing the deep zones where he excels.

one guys opinion
Run Support
To be effective in run support Moore will need to add some bulk to his frame. He has not been particularly effective in this area in college but showed some improvement in his junior season which is a positive sign. While he doesn’t shy away from contact, Moore doesn’t seek it out either and will need to become a more aggressive player as he transitions into the NFL. His speed allows him to make some plays in the running game and he generally takes good angles to the ball in pursuit. He does not shed blocks well which is indicative of his lack of strength.
Physicality
This is an area in which I’ve been generally disappointed in what Moore shows on film. I feel he has the size to be a physical player but doesn’t show it on game day. He came to UCLA at 190 lbs. and has barely added any bulk to that frame. He doesn’t bring an intimidating presence to the defensive backfield and is passive in the run game.
