When do you call inside and outside zone?

Boston College line coach blocks the full zone with two schemes, I believe they were red and white. Vs. a 3-7 or 3-9, they go white. Vs. a 1-5-9 they go red. The center is reaches the one and they expect the one to pursue the play down the line. The FB has the backside 5. backside guard and tackle deuce the 3 tracking will. The playside guard and tackle combo deuce the 5 to the mike. TE bases Sam. Play is designed to cutback to the 0 hole which is vacated by the one tech mirroring the center. Interesting look to the full zone. As Coach Campbell says, play could cut all the way back. Boston Coll. teaches the backs to be patient as they read the flow then explode to the vacated space. If sam gets turned back by the TE, back and explode outside.
