The league has incrementally expanded the draft lottery process over the course of the early 2010s to discourage "tanking"—the act of deliberately losing to get a better draft pick. Historically, the league only subjected the first overall pick to the draft lottery among the five worst teams in the league, meaning that if a draft had more than one marquee prospect (a generally rare occurrence), it would still be a viable strategy to tank, as a second overall pick was still guaranteed. This was made evident in the 2015 NHL Entry Draft, where marquee prospects Connor McDavid and Jack Eichel were both seen as NHL-ready and likely to be stars; much speculation surrounded the struggling Buffalo Sabres, who allegedly tanked to secure the rights to at least the second overall pick (a charge that, although the Sabres' fans openly encouraged it, the team officially denied). Beginning with the 2016 NHL Entry Draft, the top "three" overall picks are subject to lottery among all fourteen teams that did not make the playoffs, meaning the last-place team will only be assured of the fourth overall pick, at which point virtually any marquee prospect will have already been selected.
