Your biggest issue at this spot is inconsistent playing time, plain and simple. Bargo and Chapman are really the only two that should be considered ( I could entertain arguments for some Peebles due to his both sides of the plate approach he offers), they have shown that they can hit both mid-week and conference, Backus has not.
Bargo hit his best when he was consistent in the lineup, even though he didn't start he was almost guaranteed a swing, same with Chapman when Ensley was struggling (more on that in a second). Bargo hit lights out and fielded extremely well during BA's absence but was immediately replaced once there was a slight down turn and that is when Chapman entered the scene more consistently and then it turned into the same thing, a never ending cycle of DH tom foolery.
So about the Ensley reference, he is a prime example as to what CTV should have done with Chapman and Bargo, keep them grinding and ride it out and you will have consistency these two are to good not to find it, imagine the mind %u#k these two and the others are going through each at bat to try to do something special in hopes that they get more playing time instead of playing their normal game which landed them in Knox in the first place.
just my 2 cents while waiting for the end of work week whistle to blow.
