Contract Year Phenomenon
Contract year phenomenon is a term used in North American sports to describe the occurrence when athletes perform at a very high level in the season prior to their free agency eligibility. In the NBA, a study showed that Player efficiency rating (PER) on average went up during the player's contract year, but then dipped below baseline the year after signing said deal. Also, while blocks and steals did not increase during the contract year, they still significantly dipped below the baseline the year after. In the MLB, when averaged across the population there was no significant improvement in statistics during players' contract year, but various metrics for batting were shown to drop off the year following the new contract. This is in line with recent psychological theory that suggests salient external motivators (like a large monetary contract) may work to undermine intrinsic motivation (and thus performance). The contract year phenomenon is most associated with the NBA due to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Player Efficiency Rating
The player efficiency rating (PER) is John Hollinger's all-in-one basketball rating, which attempts to collect or boil down all of a player's contributions into one number. Using a detailed formula, Hollinger developed a system that rates every player's statistical performance. Introduction PER strives to measure a player's per-minute performance, while adjusting for pace. A league-average PER is always 15.00, which permits comparisons of player performance across seasons. PER takes into account positive results, including field goals, free throws, 3-pointers, assists, rebounds, blocks and steals and negative results, including missed shots, turnovers and personal fouls. The formula adds positive stats and subtracts negative ones through a statistical point value system. The rating for each player is then adjusted to a per-minute basis so that, for example, substitutes can be compared with starters in playing time debates. It is also adjusted for the team's pace.
