At the risk of turning this diary into a flame war between Red Sox fans (the Yanks have too much money) and Yankees fans (the Red Sox have a lot of money too), I'd be interested in hearing from people who have actually seen Matsuzaka pitch.  (And yes, we've all seen those grainy Internet videos.)

1. What kind of stuff does this guy have?  For years I heard about the gyroball, now that's apparently something of a red herring.
2. From pictures, he seems of slight build.  Has that been a problem for him in NPB?  Using the same projections we'd use in evaluating prospects, do people see that being a problem for him in terms of either injury or effectiveness in the majors?
3. What's his composure like on the mound?  His command?
4. Finally, if you had to pick a MLB pitcher to compare him to, past or present, who would you pick?
