That chop block technique

I'm seeing a lot of folks saying that's the way it's taught.

Several guys are saying you aim for the thigh pads.

All of the ones I've seen that injure guys are when the blocker puts his eyes down and throws himself at the defender. How do you hit what you're aiming for if you're ducking your head and rolling into his legs?

You mean to tell me that these coaches are teaching players to lunge at the defender and make sure you throw yourself at the target without seeing where you're hitting? I'm not buying it.

Every one of the injuries could be avoided if the blocker has control of his body and can see what he's hitting.
