Not sure how you might be hurting yourself with Dunn and Konerko. I'm not an Adam Dunn fan so in general I'd stay away from using him in my line up, but Konerko is a rock. His injuries last year weren't old guy stuff, he'll chime in with his usual solid production and even if he has a down year, you're looking at a healthy baseline of .260 25 80 and chances are you got him after the tenth round.
I like your team a lot. Miguel Montero is one of those unsexy names that doesn't get a lot of praise but you'll get above average production at C. Allen Craig needs to stay on the field, but if he gets 140 games under his belt this year you're probably looking at a .275-.300 average with a punchers chance of 30+ home runs. Cruz is a big value pick up this year because for some reason nobody cares about him, but with Maybin and Dunn, your BA needs some help. Get Dunn out of your everyday line up. I'm not sure Span won't out play Maybin this year so he might eventually need to get in your line up over him, but Dunn is the guy who has to go. I think people are mis-reading Michael Young, not that I'm out there gunning for him in my drafts but PHI was a great landing spot for Michael Young. He has a pronounced home road split that has a lot of people thinking he'll lose a lot of his value by not spending 81 games in Arlington. PHI is a hitters park too, and well suited for a guy who can go to all fields. He's hitting third in their line up, and he isn't a very good real life baseball player, but chances are you won't care how often he goes 1st to 3rd, how many GIDP he has, or how bad his range is. He'll hit around .280 and you need that more than you need Dunn's homers. McCutchen, Giancarlo, Konerko, Craig, and Cruz all promise HR. Plug in Young while his legs still work and worry about upgrading that UTIL spot as the season goes. Adam Dunn's BA will hurt you.
