I just got an email from Ken Roberts, who pointed me to his own playoff odds site - Sports Club Stats. Ken provides verydetailed predictions, recaps, and "what ifs." For example, here is the Indians team page. Sports Club Stats covers every major American sport and then some.
I've only known about this site for a few days, but it's already one of my favorites. Be sure to check it out to see how your team is doing in the playoff hunt!
