having the backup quarterback play as the holder has faded out in the nfl, mainly due to a rule in the nfl's collective bargaining agreement that prohibited a team's third-string quarterback from playing except in emergencies (this was repealed in the 2011 cba, but since that time, most nfl teams have only carried two quarterbacks on the active roster). however, such usage has remained rather common in collegiate football. many times a quarterback who was a redshirt freshman will serve as the holder his sophomore year. it is also common in other professional leagues such as the arena football league (where there is no punting and are thus no punters) or the canadian football league, where roster size restrictions generally result in one person serving as both placekicker and punter.
