230 is pretty light to take on blocks, that's why a lot of LBs don't anymore... or don't do it well. You see a lot more of them trying to run around the block or beat the blocker to the gap.
Sending a 230 pound man to take on a 330 pound man in a full sprint is not going to end well for the smaller guy, at least not after a few snaps of it. It's how the game is now, with speedier backers who need to cover ground.

Hopper seems more eager to take on a block than Cooper, but Cooper likes to shoot gaps and is so fast. They will both be aggressive and can run. I think Hopper is easily LB4, but ILs get hurt a lot so he'll play. I hope Hopper plays as well as Dennis Hopper acted. He was a hoot in Blue Velvet.
