My understanding is that was to protect defenseless kickers, holders and long snappers. Not quite the same.No. You can stack offensive players but they banned doing the same on defense in the name of "play safety" on FGs and such.
I don't know how you could officiate that, sometimes the hole doesn't open where it is drawn up and the blocking back runs straight into an o-lineman's back.Sounds like Goodell wants the tush push banned or a "source" has said at least
