A QB can lift his leg in both the shotgun formation as well as from under center. In the shotgun, generally, it’s a timing cue for the center to snap the ball. When the QB is under center, the leg lift is generally indicating to players who are split wide in the formation that they can start “in motion”.
In games which are broadcast on television, radio, or over the Internet, each team is granted one 60-second timeout and four 30-second timeouts per game in addition to the media timeouts each half. High school basketball allots five time outs per game, with three 60-second and two 30-second time outs.
