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.
