How Well Did Roger Clemens Age?

I wrote several posts on this back in February 2008. Since he has been indicted, I guess this might be relevant again. My idea was to see if he performed better as he aged and if he did, was it unusual. My take on it was that although some of his "old-age" performances were unually good, there were some other pitchers who show similar late-career improvements. Here are links to all of those posts:

I also wrote a couple of articles called "Did Roger Clemens Have the Best Age-Adjusted Season Ever in 2005?" (parts 1 and 2) a couple of years ago. You can read them here and here. Again, the evidence was mixed and it is not clear anything unusual happened then.
