The Nike/NewEra deal with the NFL will do into effect after the 2011 season (if there is a 2011 season). Will be formally approved by the owners and announced this week.
adidas made a bid they felt they could make money on, which would have been a combination of the adidas and Reebok brands. It's no big secret that these deals are pretty much money-losers for the company, even with the massive amount of gear that an exclusive license can move. The NFL contract was the only sponsorship in the adidas portfolio that was a money-loser.
Under Armour will retain its sponsorship of the NFL combine and draft, but could raise enough cash to even make a provisional bid. The dollars the NFL was looking for were absolutely ridiculous.
