Will the 'Tush Push' Be Eliminated?

"To me, you have to take all of those rules holistically. What effect does one rule change have on the next thing? So, if you take out the 'tush push,' then you're going to take out all pushing," Harbaugh said.

"A guy can't be downfield, and the offensive linemen can't come running in and push the ball carrier five more yards. You can't take one out but not the other. They are the same, just like you're not supposed to be able to grab a running back and pull him into the end zone. That hasn't been officiated. They've allowed that to happen. That's already against the rules. How are you going to officiate that? So, if we want to say that you can't help push a [running] back, then you can take out the 'tush push.' If you're going to say that's still allowed, then, in my opinion, can't take out the 'tush push.'"
