Play board
Build your own diagram. Pick a personnel group and a defense, then drag the players where you want. Tap an offensive player to give him a role (X, Y, Z, F, H) or to draw his route and pre-snap motion. Press play to run it. Pause at any moment, tap a spot on the field and press Pass to throw the ball there.
To draw a block line, pick any player, offense or defense, and press Block. The line ends with a short bar.
Defenders show their positions: DT and NT are tackles, DE is an end, M, W and S are the Mike, Will and Sam linebackers, CB is a cornerback, SS and FS are the safeties. X and Z are the wide receivers, Y is the tight end, F is the flex player (a slot receiver, a second tight end or a second back) and H is the running back. Your board is saved on this device.
