As for position players, he'll probably want an Ausmus/Matheny type of catcher. He might want a fly chaser in CF. Corey Patterson? Votto would seem to be the guy in the most tenuous position, followed by Encarnacion.
He's likely to love Phillips and Gonzalez. I suspect he'll be good for Dunn, not tampering with him too much, not hitting him too low, getting him to play loose.
Jr. is the real question. Nominally, he's the obvious candidate to go, but will Dusty insist on keeping him?
Possibly the plan could be to deal Votto for an arm and station Dunn or Jr. at 1B.
