It wasn't only for Surface. The NFL deal was fairly broad, touching on Xbox, Surface, Skype, and more of Microsoft's consumer products and services, as well as being an official sponsor of the NFL. Mattrick was one of the primary figure heads for it, but I'm sure it was a big team effort across the E&D divsion.
The Entertainment and Devices Division was led by Robbie Bach, with the Interactive Entertainment Business (e.g. Mattrick's team) rolling into it. IEB led all things games, movies, TV, and music for Microsoft's consumer products. There multiple hardware development teams and a centralized services team within the overall E&D division.
If you want a trip down memory lane and want to hear Mattrick talk about the deal for Xbox:
