At least one thing about Andrew Wiggins' transition to the NBA will be nice and simple: the one-and-done Kansas University product will continue to play basketball in adidas shoes.

The official outfitter for KU athletics through 2019, adidas announced a professional partnership with Wiggins, Cleveland's No. 1 pick in the 2014 draft, on Wednesday morning.

At about the same time, Wiggins shared the news via his Instagram account.

ESPN's Darren Rovell first reported the endorsement deal Tuesday night. His sources said the multi-year contract guarantees the incoming rookie at least $2 million a year.

In a report on Forbes.com, Darren Heitner revealed the contract includes a provision that would allow him to opt out of it and "revisit the marketplace" before the deal expires.

Heitner spoke with Wiggins' agent, Bill Duffy of BDA Sports Management. The agent said the contract included a confidentiality provision, meaning specific money figures couldn't be disclosed. But Duffy told Forbes it's "safe to say it's the greatest rookie contract adidas has ever done in basketball." According to Heitner's report, the deal includes a royalty scale designed to compensate Wiggins as he grows as an NBA player.

As part of the agreement, outlined by Forbes, Wiggins will make international trips and other appearances for adidas throughout the deal.

Rovell wrote Wiggins became the first No. 1 overall pick to sign with the company since Chicago's Derrick Rose, in 2008.

Duke's Jabari Parker, chosen one pick after Wiggins by the Milwaukee Bucks, signed with Nike's Jordan Brand before the draft.

Some speculated Wiggins also would sign with Nike, especially when he wore a pair of old school Jordans the first time he put on a Cleveland uniform, as part of his introductory press conference — photos from which can be seen on Cleveland's website.

But the Forbes report stated Wiggins and adidas "had an idea they would be bound by a contractual agreement for a few weeks."

Now that the 19-year-old from Vaughan, Ontario, Canada is a professional, Wiggins also has rolled out his own website: andrewwiggins.pro. It provides links to his social media accounts, a look at his own personal logo and, in general, information on all things Andrew Wiggins.
