I guess it kind of depends on the angle of his heads impact...Kind of weird comparing it to Dale Earnhardt's wreck in Nascar but that didn't look like a hard hit at all and it ended up killing him cause of the angle of the impact of the crash...It seemed to have a big impact on Griese
There was no reason for Kirkland to jump on him like that. He slid, and all he had to do was touch him. I expect Kirkland to get fined, as the NFL will fine any hit that causes injury. It was a clean hit, but was unneccesary.
