This isn't a triple option. The backside Aback is blocking inside out on the corner and the pitch goes to the BBack. If TM charges and options off the read key #40, then the pitch goes to Mason and #40 is out of the play.
I know this isn’t a 3O. However, the pitch to the B-back is simply not available because #40 is going straight towards him and only switches to TM after he is convinced TM is keeping it. The reason I believe this is that when #40 focuses down on TM, he is behind him, almost between TM and the BB.
Have we run a similar play successfully in the past? I get what you’re saying about the possible 5 yards that exist for the BB, but the angles just seem all wrong for a pitch to the BB. The BB is hardly running forward and continues to move parallel to the line of scrimmage (at least the corner the playside AB blocked appeared to think so, since he went wide of the AB, expecting the BB to come onwards the sideline). Further, the BB is so far behind the line of scrimmage, running parallel to it, I find it difficult to believe he would be able to turn downhill and get even the 5 yards, esp since #40 would have a great angle at taking him down.
The pitch to the BB may have been the best option, but it’s hardly a good one, and with#40 appearing to focus down the B.B. for the most part, I don’t see what would lead TM to believe the pitch was the right option.
Even the late forced pitch once #40turns towards him does not appear great because #40 is right between TM and the BB.
I mean, this play appears all sorts of broken. It would be cool to compare to some other similar plays we may have run to see what was supposed to happen.
