Joey, you explain this well enough to almost make me actually consider it. I think trading Dickey is reasonable, but moving Wright could be foolish. I suspect you value Wright, more than most fans, which is probably why you imagine him bringing back meaningful prospects.
In my view, Wright has significantly more value over the next seven years to the Mets (as a hitter, as a third baseman, as a guy who knows and plays well in New York, as someone to market and someone to guide young players) than he would have in any trade, because there is no guarantee those prospects will ever pan out. I'd take that bet on Dickey, because I think his age and the mileage on his body limit his upside, yet he'd still net good value in trade because he's a pitcher making little money.
Of course, I'm not as pessimistic about 2014 as you, it seems. The team will likely have around $50 to $60 million committed to that year's payroll, entering that off-season. I trust they'll keep payroll around $100 million, as it's going to be in 2013. That means lots of money available to build on Wright, Ike Davis, Jon Niese, Matt Harvey, Ruben Tejada and whatever other players they deem worthy of moving on. So, I'm not willing to give up on 2014 before 2013 has even started. Because of that, Joey, despite your sound argument, I have to keep Wright. The team will need him for the reasons I mentioned above. They can get prospects for Dickey, but I'm convinced Wright has to be here.
