all i try to say is chemistry.
it is very important, we saw this in 2004.
rentaria is a good player but couldn't fit in red sox, cabrera probably wasn't better player then him but he fit very well.
we have to wait and see how pena is going to do, actually this is not only for pena, for rest of the new players too, including crisp.
and wells; sorry guys but i will be honest, i really don't want to see him under red sox uniform, he has to play in yanks with his bambino's hat, that's my personal opinion.
