It all depends on the personnel, but one of the great things about zone, is that you get more eyes looking forward at the ball. So it can limit big plays and increase interceptions and fumble recoveries.
True but unless you have that one guy that commands a double team,then the QB standing around and wait for the wideout to find the holes in the zone. How Many times have we seen drew find zones in the zone with all day in the pocket?? Without great pressure zone defense the QB has time to look at his first second and third option.
