I don't know who the next basketball coach at Indiana University will be, but I predict a long and healthy relationship. I base this not on sports knowledge but on my understanding of the rules of breakups. The No. 1 rule is: The first relationship you have after your heart is broken is never a permanent one; it is the interum affair, the placeholding fling that you enter into lightly while you mend. Mike Davis was the post-breakup beau; he was never destined to be the next true love.
