Resting the starters

Resting the starters is the substitution of regular players on a sports team with backup players, and it occurs when a team has clinched at least a playoff berth, often its division, and in many case home advantage, and no further regular season losses would hurt the team in the standings. This enables the team to avoid risking injury to the starters, and to give real life playing practice to backup players.

Veteran starters are also frequently rested in the final preseason games in order to get them ready for the early part of the season. Also, starters are sometimes rested during a game during garbage time when the outcome is mostly certain.

Effects on players and team
The debate on whether or not it is a good idea to rest starters has not been resolved. Some analysts argue that it is good for the team by enabling the bodies of the players to be fresh, while others state it could make them more rusty.

While resting starters may have the advantage of preventing injuries, it may deprive them of various statistics they are trying to accomplish, particularly individual season records.

In sports with a small number of games per season, such as gridiron football, there is also the argument over whether it is better for a team with a perfect record up to that point to rest players or to try for the perfect season. For example, the 2007 New England Patriots did not rest their starters and accomplished a perfect 16-0 regular season in a victory against the New York Giants (who also played their starters), but ultimately lost Super Bowl XLII to the same Giants team. The 2009 Indianapolis Colts, after going 14-0 and clinching home field advantage throughout the playoffs, rested their starters and lost the final 2 games. They made it to Super Bowl XLIV, which they lost.

The 2011 Green Bay Packers rested their starting quarterback Aaron Rodgers on the final game of the regular season, as the Packers had already secured the #1 seed in the NFC playoffs. Combined with the bye week earned with that seed, it would be a total of 3 weeks before Rodgers would play in a game again. The Packers lost their subsequent Divisional game vs. the New York Giants, leading commentators to wonder if the extra time off had been a detriment to Rodgers, as several crucial passes were dropped by the Packers in the game.

In 1993, the National Football League experimented with a two-bye week format. After the success of expanding the regular season to a period of 17 weeks in 1990 NFL season, the league hoped this new schedule would generate even more revenue. However, teams felt that having two weeks off during the regular season was too disruptive for their weekly routines, and thus it reverted to 17 weeks immediately after the season ended. The negative effects of having two bye weeks can be similar to the negative effects of resting starters, as having several weeks off (in the case of a division winner, several consecutive weeks off), a player's routine can be hurt.
