Taggers Taggers, also known as run-with players or stoppers, mark the opposition's best player (often a midfielder, although sometimes a half-back) and restrict their impact on the game. Good taggers must be fit, disciplined and focused. They must be strong enough to keep their position in stoppages and contested play (without conceding free kicks), yet fast enough to match their opponent's spread. Notable taggers include Ryan Crowley, Steven Baker, Brett Kirk, Cameron Ling, Kane Cornes, Ben Jacobs, Brady Rawlings, Shane Heard and Matt de Boer. Interchange bench Players named as the interchange, also often known as the "bench", are not permitted to enter the field of play unless substituting for a player during the game. Up to four players can be named on the bench; this number has steadily increased from a single player in the 1930s. Representative teams (such as State of Origin teams or honorific teams such as the AFL Team of the Century), practise and exhibition matches often feature an extended interchange bench of up to six or eight players. Until the 1970s, the single interchange player, known as the "nineteenth man" or the "reserve" acted only as a substitution for an injured or out of form player; the player substituted out of the game could take no further part. Since the 1970s, interchange has increased from two to three to four players, and substitutions may be made as often as the coach wishes, with players allowed to be moved onto and off from the ground for several rests during the game. The four players named on the interchange bench in the teamsheet (which is submitted ninety minutes before the commencement of the game) must actually start on the bench, however they may be substituted immediately if the coach wishes. Substitute From 2011 until 2015, the AFL level interchange rules provided that each team was permitted three interchange players (instead of four) and one substitute player. The substitute sat on the bench and began the game wearing a green vest over his playing guernsey. He was not permitted to enter the field of play, nor be interchanged while wearing the green vest. At any time during the game, he could be substituted for one of the other players in the team—either on the ground or on the bench. He took off his green vest, and the player he substituted put on a red vest. The player in
