Butler, Beltre & Lawrie. Lawrie has upside but I think is a year or two away from getting there so keeping Beltre to play 3rd while Lawrie matures would be wise.
I like Jones but like I said to someone else, he had 1 good year (now show me another so I know it wasn't a fluke). Same thing goes for Headley.
As for Molina, the catcher position is deep so don't worry about losing him (especially in an 8 team 1 catcher league).
