I'd do this trade for Conforto plus their choice of any pitcher whose last name has ten letters or fewer. I usually don't like big contracts unless (a) the player isn't some aging slugger or speed demon who has a good probability of turning the last few years of the contract into a major albatross, a la Reyes, Howard, and Pujols and ( the player can transform a pretty good team to one of the best in the majors. It's not worth the big bucks and commitment to turn a last place team into a third place team. But, whaddya know, (a) and ( both apply here. And 5 years/$138M isn't all that yuge for arguably the best player in the majors, and someone who would fit well into the Mets' lineup if Conforto were part of the trade. Conforto and Matz are both likely to become really good players for a really long time. But it's a good bet that their combined value won't ever approach Trout's. And, sure, they're bargains, but the Mets have plenty of bargains right now. I like to think that they can take on one more big contract (yeah, I know, Wilpons...but one can dream, right?). As far as a lefty starter to replace Matz in the rotation, Sean Gilmartin is currently 4-1, 2.48 in the PCL. He's no Matz, but he'll do.
