For the old timers on here

Thanks. I watched it IRL. The worst hit was not on that video. Butkus hit a Green Bay RB named Tom Moore on a screen pass. I thought Moore was going to die. They carted him off on a stretcher. Butkus said "I don't tackle the running back. I tackle something two feet on the other side of him."

This is exactly what is missing from the NFL.
This was when it was fun to watch the NFL.
When players had a bit of chip on their shoulder.

Add Ronnie Lott to that. Hated the Niners but he was an animal.
