Don't buy it. Dickey is not only dominant but he's an innings eating machine. You toss him aside and suddenly you're putting a burden on the young pitchers that they never had to worry about before.
And of course, that translates to more work for the bullpen. we know where that will lead.
I'm sounding like a lone voice in the wilderness now but the Mets would be making a huge mistake to trade Dickey. Sure, if they can fill two or three holes you trade Dickey or any pitcher really in a heartbeat.
But the chance of that happening is nill. More likely, they'll get prospects who are more suited for the bench than as starters.
But as the Zen Master said, we'll see.
