All in all, there's only one grand reason why trading Granderson would make sense for the Tigers: MONEY. He's making a lot of money and if the Tigers think his batting average vs. lefties is a serious problem, making him a platoon player, then he's not worth the "big" contract he received (a sad pattern for Dombrowski).
The Big Lead mentions that the Tigers want to cut the payroll, but fail to mention why Granderson would be a part of those plans. Instead they cite irrelevant precedence of the Tigers trading two other CFs (one who was not good and the other who hadn't proved anything yet) and an unconvincing discussion of filling other holes with the trade. The reasons they did nail they surrounded with balderdash.
Again, the Tigers, like most teams, are entertaining ideas right now. Of course the Yankees want Granderson. Who wouldn't? He has a powerful bat, speed, makes great defensive plays despite sometimes needing a GPS system, and he's an upstanding person.
Will his remaining potential, what he provides Detroit's offense despite his poor BA vs. LHP, his defense, and his popularity amongst the somewhat dwindling fan base be enough to make Dombrowski keep Granderson around? I certainly hope so.
I'm not sure what sort of "remaining potential" Granderson has, since we probably saw his very best in 2006 when he slashed .302/.361/.552 and showed up on some MVP ballots. But sure, he's still a fine player and easily worth the $26 million he's guaranteed through 2013.
That doesn't mean the Tigers can't trade him. It just means there's not a compelling reason to trade him. Unless the Yankees (or whoever) come along and offer the Tigers a package of two or three young players who will be worth more in 2011 or '12 than Granderson, in which case the only reason to not make the deal is the hit in the standings they would probably take in 2010.
But to what end in 2010? Another 85-90 wins (at best) and a quick exit in October? Sure, there's always the chance of a miracle ... but that's not where the smart money is. In a division with three cash-poor teams and one that often seems directionless, the Tigers should be trying to build a team that can win 90 games every year and dominate the Central like the Angels dominate the West.
