It?s official. Number one is now with Nike. We may not have a full hoops season next year, but the rookies from this past NBA Draft are still signing endorsement deals at will. Following the announcement that Kemba Walker has joined Under Armour, the first overall pick, Cavalier Kyrie Irving, tweeted that he?s officially signed on to wear the Swoosh. While it?s unlikely he?ll receive a signature Nike shoe next year, Cleveland fans will be able to watch their squad led by a first-pick rookie in Nikes next season. D?j? vu, anyone?
