I agree the Seattle could make a great trade partner, but that deal is pretty ridiculous. Seattle has something like 77 mill locked up in 5/6 players, so they are not going to add another 40 million in 3 players with Tulo, Eddy, and Dickey.
Also I could see the Jays trading one of JB, Eddy, Tulo, but I have an insanely hard time seeing 2 being dealt. Especially in the same trade.
