He doesn't need to drop his head, which he did, either. Tacklers need to be taught to bring their arms to the party.
No. Your logic is flawed and those that made it. The whole rule is predicated on a perceived fact that defensive players don't have heads on the "top" of their bodies. Which is ludicrous. Offensive runners are allowed to target all the time. The rule is selective and S.U.C.K.S.
The rule sucks. All it takes is a slight sidestep and a shoulder hit becomes a helmet hit. It's a moving target. THE RULE SUCKS!
Chickenshit prejudicial rule against the defense. I demand a recount! Get those people back in here! Turn those machines back on!
