As a footnote to the Mayo/Love blockbuster trade worked out by Memphis and Minnesota, I see that the Jayhawks' Darrell Arthur was drafted at #27 by New Orleans.
Then traded to Portland.
Then traded to Houston.
Then traded to Memphis.
There can't be many (or any?) other people who've been on four different NBA teams in the same day. I hope they all let him keep the jerseys and caps.
