Sack on Mariota...did DT commit a penalty?

Granted, Shwenke flat out got beat by his man, but Mariota had avoided him...only to get sacked by the DL that beat Levitre. However, watch what happened (to Levitre) on that play more closely. The Defender grabs the collar and basically does a "horse-collar tackle" ....from the front. Today's jersey's don't give you anything to grasp a hold of, so to be able to sling an OL like that, you have to get your hands on the collar and jerk with both hands, forcefully. That's a horse collar tackle by definition.

Is that a penalty in the NFL, and if not, why not? It's dirtier than a WR pushing off to make a catch. Imagine an OL doing that same move on any given play. They'd be called for holding all day long.

Just what a 10yr old little runt would say. Boy, I say, boy...now go run along and play with the other kids while the adults here, talk. You're getting on my nerves.

 

...going on 10 and a half. Your IQ is more like 28, and that's being generous.
