Whether he should retire or not is a matter he (and mostly he) has yet to consider, much less make a decision about. He routinely makes comments to the effect that he'll be playing at an improved level for the next 5 years. It certainly doesn't appear he's thinking in terms of considering retirement for sometime yet to come. They say players are as good as retired the moment they start thinking in terms of doing so. Perhaps it's just as well he's not considering it at this point in time. Of course, his back may demand he retire at some point yet to come but evidently, that thought isn't weighing too heavily on him at this juncture. I'm hoping his condition stabilizes in the offseason and doesn't present nearly as much of an issue next year. Only time will tell about that, of course.
