Sometime back I suggested that it will be really hard to watch Tek for another year as we do not have a replacement in place and we should go after Posada for a year putting Tek in bench. That did not go so well with the RSN, It is a sacrilage to have doubts about the captain in the nation - very similar to questioning Jeter in the Yankee team.
Varitek has been horrible offensively since ASB of 2005. In the field - he can't throw my grandmother out if she tries to steal second. But he has even sucked what his intangible asset used to be - developing young pitchers and pitch calling. For now he is safe because the bench has great players like Cash and Belli.
