In general nice guys are going to be liked to the players, and you can actually understand what Tito is saying, so I can't see why players would not like him. He definitely isnt detracting from the atmoshpere in the clubhouse.
I think, in part, the problems are due to the lack of Nomar and Trot (both prominent figures on the team, not just on the field). The team should swing things around now that they're back. Just some getting-used to it time that is needed.
