I pull up the punt return screen and over-ride. Others know that it's something like ST Rusher #3 through 5 which slot into the attack positions. (the two wings spots on the front four)
It's more rare, however, Lars caught me with a singular usage LB on a punt block and I want to say somewhere along the way Pern got me with a TE. But, yeah, if you streamline a TE or LB with a sole purpose and no other usage but to punt block - they can come in fresh and get you off timeouts or other breaks within the action for rest spots. (early in the game, penalty calls, time outs and if a couple of med/long pass sacks occur before the punt) This is way rarer than the 191 lb. CB zip lining in.
It needs a perfect storm to hit or an 88 acceleration LB barely used.
