Don't trade Roy Halladay, Blue Jays.
Not for the sun, the moon, and half the stars.
Maybe to the Yankees if they offer you CC Sabathia and Phil Hughes. Or for an equivalent offer from another team. But not otherwise, because he is the "sine qua non" (without which not) of your playoff chances.
I have been one of the people that believes your team has a legitimate shot at the playoffs, if not this year, certainly next. You got off to a good start, then faltered, mainly against (weaker) National League teams. A better "draw" next year might see you through.
