I think the hits to the head are unacceptable. Two occurred in the Browns/Steelers game. While both might be legal under league rules, they are very dangerous.
The first of those two (the one on Cribs) was not at all intentional. Harrison had committed into diving at the direction Cribs was heading before Cribs got tripped up, falling forward. If Cribs didn't start heading to the ground, Harrison hits his legs, not his head.
The game is so fast, especially when guys like Cribs have the ball, I don't know how you prevent those kind of hits. Maybe make every player wear 20 pound ankle weights to slow them down. ;~))
In the case quoting facts you state that the hits are legal and in your OPINION the hits are UNACCEPTABLE.
It's easy to see why you are a buckeye/browns fan.
Go over to namby pamby land and take the tissues with you.
Watch soccer, no pads, no hitting, no scoring, no nuttin'.
The only thing that's allowed to hit the head is the ball, but that might not be acceptable to you.
As John Madden famously said,You have to remember there are THREE teams on the field. by which he reminds us that there are way too many of biased referees in the NFL.
And some refs are simply afraid to call fouls on certain teams.
