It depends on why he's being abused. If he's being abused because he doesn't have the leg drive to overpower defenders, then that's somewhat different from being abused because you lack explosive power to pancake people, which is also different from lacking the agility to help chip one defender before moving on to block another defender at the next level of the defense. Our guys simply do a poor job of moving the line of scrimmage forward, because they can't overpower anyone. In a ZB scheme, you don't have to physically dominate anyone on the other team, you just have to be able to stand in their way and not be moved yourself. I don't think anyone is saying that either of these schemes would make our linemen elite, however, a ZB scheme would play to their (limited) strengths, whereas a power scheme requires an ability which for our linemen is their greatest weakness.
