Under Armour has presented to Kevin Durant a 10-year offer worth as much as $285 million.

Durant's represenation Roc Nation Sports informed Nike of the offer on Wednesday.

The deal includes Under Armour stock and other incentives, such a community center built in his mother's name, whose exact worth will not be known for some time.

Nike has the right to match the offer made by Under Armour and Durant could also still choose Nike if it doesn't match.

Nike's last offer, sources said, would have given Durant a base and a minimum royalty guarantee that would equal no less than $20 million a year.

Because Under Armour has such a small basketball business, the company has to guarantee Durant his money up front, instead of the typical shoe deals that offer a minimum guarantee plus up to 5 percent royalty on the wholesale revenues.
