I think the trade suits your teams needs very well. You are gaining solid consistent production from 2 of the most healthy players in the game. You also get the top available pick in the draft. You are giving up some potential - but i think lawrie is overrated and tulo has yet to play a full season while prince and andrus have not had any substantial injuries.
I don't think I make that trade. Tulo's replacement value at a thin position is hard to beat. I think Ike will have a good year, so you're covered there. Lawrie is a 20/20 candidate which is hard to beat at 3B. so you look down 140 players or so and is that player a deal maker? Probably not. I'd pass.
