- * there probably isn't a negative correlation
-
- * there's probably a slight positive one. There is a causal link, too:
- both "how the teams actually do" and "how you think they'll do" go back
- to "what the teams are like" via "what you think they're like".
-
- There can't be a true, repeatably findable correlation without *some*
- sort of causal link, with the possible exception of the passage of time.
