these kind of hits are not usually that common , but i was watching a game between Dallas and Minnesota, and i saw the quarterback get taken down from behind the line of scrimmage, and after the ball was thrown with a helmet to helmet hit. its no secret that these hits hurt, a lot... and that is usually what you expect in a football game, but when these hits have a high chance of landing you in the hospital something should be done about it. Tony Romo is young and he got back up... but it could have easily gone the other way if the hit was slightly more solid, costing a team their star player.
if one team loses a player... its only fair if the other team loses one as well... so i can see why suspension has been selected as the punishment. It does seem harsh though. I completely agree hard hits are part of the game, but it already was an illegal hit... but the current severity of the punishment has not detered it. most players seem to be able to control themselves and not fly into people head first. it really isn't an easy task to collide head first on a tackle without putting effort into it. frankly, as much as i love watching football, i would rather see it being played fair, rather than played all out... if i want that i will throw in a copy of NFL Blitz.
