I always equate Freeney to Jeff Bagwell. Wait, he's a baseball player!. Here's what I'm talking about: The Astros for years had other sluggers who put up Bagwell type numbers: Alou, Hidalgo, Berkman, Ensberg, etc. But Bagwell was the constant. If felt that his presence in the line-up set up the other guys for their good numbers by allowing them to see good pitches because the pitchers didn't want to face Bagwell. Every time I watched an Astros game, it was Bagwell they were obviously pitching around. I could only imagine what Bagwell's numbers would have been if he'd been pitched the same way as the other guys.
I think a lot of Mathis' success was the result of Freeney being on the other side and getting lots of defensive attention: he was the guy the other team was game-planning against.
Of course the Kaiser could be right. it could be along wait, just as it was for Art Monk and Floyd Little. And it would make about as much sense.
