I put a lot more weight on the opinion of people like you,
@JayCane20 and
@Memnon who have actually watched this guy play. There are also coaches from teams who play good defense (not UM) who value the player. That's the fun of this stuff, people have different opinions and we won't know until they develop.
On paper, this seems like a traits-based evaluation at a position where traits are very important. I am excited to watch this kid on Greentree and hope he develops more than other players we've had recently at the position.
