The deal includes stock and a community center to be built in Durant's mother's name. Nike does have the right to match, and if it does, Durant legally can't switch to the rising Under Armour. Rovell called the potential deal "the most intriguing" one he's ever seen, with Under Armour looking to gain its first significant foothold in a market Nike has long dominated. Forbes reports, Nike and its Jordan Brand subsidiary held a 92 percent market share last year, compared to 0.7 percent for Under Armour.
