This is probably just a coincidence, but that doesn't make it any less strange.
Cleveland Cavaliers rookie Andrew Wiggins, the No. 1 overall pick in the 2014 NBA draft, would likely be a pretty hot jersey this offseason, but the NBA Store has discontinued his No. 21 jersey.
Update: August 4 at 4:50 p.m. ET
An NBA spokesman has attempted to clarify the situation, via Brett Pollakoff of ProBasketballTalk.com:
A league spokesman told NBCSports.com that Wiggins jerseys are simply sold out. There is a temporary period on the site, before a sold out item is pulled, where it is reflected as 'discontinued.' The league said this happens for all sold out items, and the link to the page that was still live over the weekend is no longer active.
Additionally, manufacturing orders for rookie jerseys of top draft picks are placed shortly after the players are selected. NBAStore.com has jerseys for those players available as a pre-sale, and once the jersey numbers of players are confirmed, the site is updated accordingly.
--End of Update--
Wiggins has recently been in the middle of rumors about the Cavaliers possibly trading the No. 1 overall pick and others for Minnesota Timberwolves star Kevin Love.
