BoBo, this is interesting. Twice in the last week you have posted a question/issue that was specifically addressed by my Football Association within the previous 24 hours. Are you sure you aren't in Arkansas? 😀
This morning the Arkansas rules interpreter issued the following ruling on BBW while the quarterback was in the shotgun formation. Here it is:
If while in a shotgun formation, the lineman are in a three point stance, we will allow the lineman, on his initial charge, to block below the waist. If, however, the lineman are in a 2-point stance or the charge isn't immediate and the ball is snapped to a back at least 3+ yards behind the line of scrimmage, then any block below the waist will be rule illegal and there will be a penalty assessed. Just to reiterate, 3-point stance you can block below the waist on the initial charge in the shotgun. In a 2-point stance you cannot block below the waist when in the shotgun.
I for one think this is pretty good interp and specifically was driven by an series of injuries during the first half of the season.
