IGN's Nate Ahearn says:
Last year's co-op mode in Madden sucked. EA Sports knows it. I know it. You probably know it. Thankfully the developers down at Tiburon in Orlando, Florida took a step back and readdressed the methodology the company brings to cooperative football. I recently got my hands on an early version of Madden NFL 11's Online Team Play and will say that it's already looking like a massive step forward for co-op football.
