They pretend to be the left tackle to defend liberty and purposely get out of the way of the block so the offense is stymied. They don't make the sack themselves, they just fail to stop it. If it were football, we would all think they were on the take and had some skin on the game at Vegas. Maybe the house will surprise me and stand resolute, there is a first time for everything they say.
You really should learn to let it all out, don't hold back. You'll get an ulcer. Come on, tell us what you really think! ;-)
