re: Are LB too small?

These smaller faster LBs are too slow diagnosing plays. They should be engaging Olinemen in gaps plugging holes but instead are being engaged by the Olinemen 2-3 yds downfield and cant shed blocks until RB goes past them.

Dline is doing less penetration too. I cant tell if this is by design because they are worried about LB play or if Dline is unable to blow up blockers. With the size and athleticism of 9 and 90 I'd assume the former.
