I don't think it's very good. It activates during pass rushing, and success is based on strength and agility. But mostly strength. First you break the block (strength+agility), then if your strength is much higher, you push them back and can go around them (with speed and agility). But who does it activate against? Mostly linemen and TEs probably. Occasionally FB and rarely on HB. Against a HB yes it should work. But how often does that happen? Compare to a piece that gives a % bonus which is active on almost every, or an SA bonus that can help get the bonus to 9 or 10 (monster hit, d-gen, even diving tackle or deflect pass).
