I will admit, it's hard from that angle to tell if it was helmet to helmet at all. It's still illegal to "launch" yourself at a guy and leave your feet isn't it? "Launching" can be a fine/suspension worthy play if it's deemed bad enough, right? Launching is illegal in certain situations, like with a defenseless receiver, although doubtful with an open field block. But much like the Steltz hit on the guy laying near the sideline, it's a play that is generally accepted as part of the game but completely unnecessary and should be banned.
