Could they be thinking they honestly think the two combo'd back together can bring back the magic? It doesnt normally happen in the past, when other combos tried the comeback.
With Ryan only having a one year contract, maybe they arent to confident in bringing Ryan back after 2013 so why go spend money on a new CC for him, using Matt as a Bandaid for a year. Will they use Ryan as a dead duck next year.
Or maybe they are filling in the year with Matt because I remember Zippy saying they were waiting to talk to others under contract. Maybe they cant get the CC they want until 2014.
