I hate it, too. I am on the record as favoring a return of the "helping the runner" penalty for teammates intentionally pushing a ball carrier forward.
And maybe @MileHigh or another officiating/rules expert can help answer this one: Isn't pulling the runner forward still a penalty? I thought it was but in the past couple weeks I've seen plays in both NFL and college games in which a lineman has blatantly grabbed and pulled a ball carrier over the goal line for a touchdown, with no call.
Correct, you can't pull the runner. You can push the pile from behind. I've been on the field twice for it in a high school game. I'll see if I can find a clip.
