From The Sports Business Journal:

With the deal ending, sources said that the Yankees originally tried to sell Nike a signage package, but that Nike was more interested in other rights. Consequently, Nike’s deal with the Yankees is short on branding and long on marketing. Nike will be able to increase the amount of team apparel it already sells as an MLB licensee and it will have a store-within-store shop at the new stadium. It will also run local marketing campaigns, grassroots initiatives, and outfit Yankee coaches and minor leaguers with cleats and other performance wear.
