Buried in an item from Jason Cole of Yahoo! Sports regarding the latest fresh start for new 49ers offensive coordinator Mike Martz is a back-and-forth between Martz and CEO Matt Millen regarding Martz’s performance as offensive coordinator in Detroit during the 2006 and 2007 seasons.

“[Y]ou have to control what Mike is doing during games,” Millen said.  “Mike is brilliant.  He can break down what a defense is doing faster than anyone I have ever seen.  Then, all of a sudden, he’s coming up with a bunch of new ideas about how to attack that defense right there on the spot.  That’s great, but you’d sit there sometimes and wonder, ‘Hey, what happened to all the stuff we talked about Monday to Saturday?’”

Martz, of course, responded.  In so doing, he threw a gratuitous barb at Millen for his habit of taking a few days off most weeks to return to his home in Pennsylvania.  “How would Matt know what we were talking about Monday to Saturday since he wasn’t there Thursday to Saturday?  The guys on that coaching staff know why we did that.  Look, we just weren’t a good football team at that point.”

And there’s further proof of Martz’s biggest flaw:  He has insufficient control over the connection between his brain and his mouth.  In the past, Martz’s words (public and private) have contributed to the creation of a perception that he’s a power-mad tyrant whose only objective is to become a head coach again, and then take the place over.

The problem is that this reputation makes it nearly impossible for Martz to become a head coach again, since those who would be in a position to hire Martz would likewise then hope to not see their jobs threatened by him.  Martz is smart enough to know this, and he’s saying what he can to try to reverse it.

“The stuff that has been said about me behind my back is really hurtful,” Martz told Cole.  “I’m here to be the offensive coordinator and to help Mike [Nolan] and this offense be better.  That’s all I’m concerned about right now.  I’m not thinking about being head coach again.  That’s not my focus . . . all the things that people say, it really angers me because it’s not productive.”

No, it angers him because he can’t control it.  And because he knows that, at a certain level, it’s accurate.
