It's not a trigger if that's what they were thinking/planning all along. If they project BV as a starting catcher with all this control, then trading Kirk before his value plummets is smart business. Adding Sprock who looks to be a Joe Mauer type just adds to the depth that will be needed. It does appear though that this trade was to good to give up in their eyes as Ross isn't ready to sell yet, not by a long shot.
