Not too shabby.
I know what you mean about Wilson, but he will give you speed, which you recognise is a problem area.
Also, I think Looper will have a great year with many more save chances, so he & Ryan are an OK bullpen.
Keep Dempster until you see what happens in Spring Training, you can always drop him for a good MR if necessary.
But the big thing is speed. I'd try shopping Dunn around (you have plenty of power), and see if you can persuade someone to part with Pierre, for example.
