i've wondered the samething. he may be on 870am from time to time, but i haven't seen him on here much. i can't remember the last he did the "ask mike" e-mail update. I know that Jeff Duncan has been very helpful with the updates for us.
Mike is always willing to answer "Ask Mike" questions, the problem is, we don't get many worthwhile questions to send him after the draft or during the season. Go to the Ask Mike board and post/submit some questions to send him.
