The format of an A-Day scrimmage is not like a regular season Alabama football game. QB’s are stopped by a defender’s tag. Plays are even blown dead before a tag when an unimpeded tackler is bearing down on a QB.
Tags are also used for kick returns. When the teams are split, theoretically one side is the first team offense, playing with the second team defense. The other side is the first team defense playing with the second team offense. Every year a few players compete on both teams during the game.
There will be a winning team and a losing team.
