On this day in 1967, the Boston Celtics lost three players to the expansion draft held to populate two new teams being added to the league.
Those teams would be the San Diego Rockets and Seattle Supersonics, the former now relocated in Houston, Texas as the Houston Rockets, and the latter now the Oklahoma City Thunder since 2008.
Expansion drafts function similar to the regular draft, except the team or teams joining the league can raid the rosters of existing teams save for a certain number of “protected” players each team can prevent from being drafted away to the expansion team or teams.
