My thought on Harris is that if he is going to be given another chance than I hope there is a suitable fall back option in place right away. Last year's fall back will be the starting shortstop and Wilson Valdez and Robbie Alomar aren't acceptable.
I'm with the consensus on Davis too. Whether or not this stat matters, of all the catchers The Sox used last year: Olivo, Alomar, Burke, Davis; The pitching staff had the highest ERA when Davis caught.
