Normally, I would scoff at this idea. I love AE, and I wouldn't like to lose him. Plus, Tejada has a big contract that would be hard to swallow.
But I LOVE Miguel Tejada! You could even say it borders on a man-crush. I would love to see him in blood and mud. From most accounts, he's a great player on both sides of the ball, a good teammate, and good in the community. I've loosely followed his career since he came into the league, and he's become one of my favorite non-Astros. I don't know if the Astros have any interest in him, but I hope they do.
Edit: The media seems to be pegging Boston as the most likely place for Tejada to go because of the void they have at SS and the fact they are Boston, but I'd be surprised to see the Orioles trade him within the division.
