i think that's a fair trade mo. young is a bit better than doumit, but you get rid of someone you don't need for someone you do need. pap is a bit of an upgrade over soria because of the team he plays for. both are great closers to have though. then kins for votto/vic is pretty fair. kins will be a top 3 2b this year unless he gets hurt and very possible he ends up as the #1 or 2 2b. votto started off hot, but he will have cold streaks that really kill you.
i think you got some very nice high end players and ttp added some very nice depth to his team. it was a very fair trade, although it's a bad trade for ttp if he considers kins a top 5 overall guy? he's not, but if that is how ttp sees him not sure why he tried so hard to trade him.
