From what I've read, here are the reasons Clemens signed with the Astros,
1. He's evil. It's a widespread contention.
2. He has to be around Koby all the time. Apparently Roger is Laura from the Glass Menagerie and Koby is as fragile as a glass unicorn.
3. He loves money. Astros offered him a million more than the Red Sox, or >5%[edit] more $$
4. He wants to be in Houston. Yankees reportedly refused the opt out of games when he's not pitching clause.
5. He is unfamilar with the Baseball Traditions of the East Coast
6. He's afraid of AL hitters.
What is not being argued, except by Clemens and Purpura
1. The addition of Clemens gives the Astros a distinct possibility of having the best rotation in the NL
2. The addition of Clemens gives the Astros
a chance to compete in the post season. Apparently a certainty is all that is permissable.
As for Pinwheel, he's now calling himself shrewd because he "predicted" the part where Clemens signs with the Astros, but allows that he got the date wrong. Of course his "prediction" was a bold one, not the least reason being that he predicted both outcomes, As Zipp mentions, but he was apparently in a minority that only included, "...several baseball executives" (who had) "long believed this was a one-team race."
