Won't be long until they bring out the belts with flags.
Take a page from Soccer, if it meets the criteria for targeting but isn't crazy then give a yellow card. If it is obviously an attempt to hurt someone then give a rd card. Two yellow cards means a red card (ejection).
I saw that last night and couldn't believe they waived it off. It was worse than what Alontae did and the LSU player didn't get penalized. That told me there is definitely some bias in the replay booth in the SECVirtually the same play that knocked out Alontae happened in the Bama-LSU game and guess what? It was waived off, no penalty. When a kid ducks or slides and the defensive player who was already going low hits him in the helmet there has to be a way to make that a no call.
IMO, they need to break it into 2 penalties. Flagrant, intentional targeting should carry the current penalty. Spear a guy with your from a running start? That deserves an ejection.
Incidental and/or unavoidable helmet to helmet contact should be a 10 yard penalty without disqualification. Hit a guy with your helmet as he drops down to try to duck under a tackle? That doesn't merit ejection. Should maybe still be a penalty to discourage any helmet to helmet contact, though.
