The Jays are not in any financial trouble so if there is an opportunity to trade Estrada, Bautista, and Liriano, then just eat up the remainder of their deals and see if that increases the package you get back. Still probably won't get that much back but might make teams more willing to give up something useful.
But yeah, I'm disappointed in how those three have performed, especially Estrada who looked like a massive trade chip about a month ago.
