This is what I saw.
Pros:
Long and rangy. Has good range when dropping back on pass plays
Long arms which helps him with wrapping up when tackling.
Seems to know where he is supposed be. Didn't see him out of position much.
Good at getting underneath the blockers for a tall guy.
Cons:
Lacks pop. He may have the size of Rolando but doesn't have the pop RoMac had. Didn't see any tackles where he drove a player back.
Lacks lower body strength. Plays light for his size.
Tends to tackle high at times. Uses his arms more than his legs to make a tackle.
Didn't see him shed blocks much once an OL got on him.
He probably will have the most impact as a cover LB in his rookie year. He needs to get stronger in his lower body and learn to use his legs/core more to his advantage.
