re: Short side option & play calling in general

All plays, besides the obvious few ST, QB sneak and V formaton are designed to score if executed properly by every player, especially WRs.
There are plays with a higher TD percentage, like flag, post plays, etc, but are all or nothing for yardage and have low success percentages.

SSO is just something parrots like to harp on, even from way back when the Option was was king.
To always run away from the boundary would show tendencies.
It can be tougher maintaing blocks wide side as todays faster LBs and DBs have more room to recover.
It is often an audible if the D overloads one side. This was pretty much the game winner 11-5-11.
