You can't base your lineup and defensive alignment on offense alone. Leaving Dickerson out of the equation as the CFer, Far East, subs a great Rf defender into CF where he is average or worse, and replaces that good defense in right with an average or worse fielder.
I want more offense too, but Gomes at first right now instead of Hernandez would help. Then you can rest Hanigan or have a good PHer on the bench and you're back to a great catching tandem. Sub Dickerson in CF for Taveras, and you improve defense AND offense. Play JHJ at short where he looks far more comfortable, sacrificing a bit of defense for a bat - but I don't think the dropoff is all that great from AGon anymore. Send Rosales down and try Sutton on the bench. Defense at third has been the weakest spot so at least maybe Sutton can provide a better bat - he can't be worse than JHJ at third, or you can be crazy and try Janish with that rocket arm - giving up a bit of offense for the glove making the defense even tighter than it has been - on the theory you go all out to help the pitchers right now since offensive shuffling is just a band-aid with this roster, at least until Votto and EE return.
Dusty, however is anything but creative. He may be the least inventive manager I've seen. He has a book and he'll keep trying to force players to fit his scheme instead of scheming to fit his players into their best roles.
