The general consensus of every rumor about Felix Hernandez is that he will be traded to the New York Yankees for a package consisting of Jesus Montero and a few other prospects.
What baffles a lot of Seattle fans is that a lot of the rumors expect the Mariners to trade Hernandez to the Yankees for virtually the same package they turned down when they traded Cliff Lee last year.
Why is that baffling? Because Cliff Lee is 32, and he was a half-year rental. Why on earth would a team refuse a trade for a player who is a half-year rental and then turn around and accept the same package as was previously offered for a 25-year-old pitcher who has three years left on his contract? How does that make sense to so many Yankee fans?
Montero is a player without a position, which means that, more likely than not, he will be a career DH because his only value is in his bat. He's a two-tool player: He makes good contact and has good power. He can't stick as a catcher because defensively he's no good. He could be a first baseman but the Yankees are set there (and so are the Mariners, for that matter).
Then there are the "untouchables" of the New York Yankees farm system: Manny Banuelos and Dellin Betances, both of whom project to be good pitchers, possibly No. 1 pitchers. The problem with that scenario is that—more than any other top prospects—pitchers more often than not don't work out. Injuries are a part of that, since an arm injury is much more career threatening and career altering for a pitcher than it is for a position player. Not to mention that most Yankee fans want to hang on to one of these pitchers, meaning the M's would only get one of them.
The rest of the package is mostly filler and B prospects.
Nothing that the New York Yankees have is something that will help the Mariners contend any sooner than what they already have. They have pitching prospects who project as aces. They have players with no position who haven't yet proven they can hit big league pitching. They have a whole slew of B prospects at their disposal.
What's the incentive to send the best pitcher in the AL to the Yankees?
