Bookmakers in the early 21st century accept bets on a far wider range of sports-related propositions than ever before. Thus, a gambling-motivated fix might not necessarily involve any direct attempt to influence the outright result, especially in team sports in which such a fix would require the co-operation (and prerequisitely the knowledge) of many people and/or perhaps would be more likely to arouse suspicion. Fixing the result of a more-particular proposition might be seen as less likely to be noticed. For example, the disgraced former National Basketball Association referee Tim Donaghy has been alleged to have perpetrated some of his fixes by calling games in such a manner as to ensure more points than expected were scored by both teams, thus affecting "over-under" bets on the games whilst also ensuring that Donaghy at least did not look to be outright biased. Also, bets are increasingly being taken on individual performances in team sporting events, which, in turn, has seen the rise of a phenomenon known as spot fixing although it is now unlikely that enough is bet on average players to allow someone to place a substantial wager on them without being noticed.
