During a “Chalk Talk” session held for fans at an event in Tahoe, Nevada, 49ers offensive coordinator Mike Martz didn’t discuss only the strategies for making the O’s run circles around the X’s.

He also shared some thoughts about the Detroit Lions, the team that fired him after the 2007 season.

In Detroit we were not a good football team,” Martz said.  “We were last in the NFL on defense and when you have to throw the football to win, that’s not a good thing.  We weren’t good enough on the offensive line to protect [quarterback Jon Kitna] and throw the ball like we did.  When I was with the Rams, we were.  The number of hits on the quarterback when I was with the Rams near the end of my time there was about the middle of the pack.  In the early goings, it was actually very low and we were ranked near the best in the league.”

Okay, fine.  A team needs to have blocking to be effective on offense.  Then why did the Lions choose receiver Calvin Johnson with the No. 2 overall pick in the 2007 draft instead of left tackle Joe Thomas?

Sure, Martz doesn’t have final say in such matters.  But we’d love to know whether he wanted Johnson or Thomas.

Or maybe whether he advocated for help on that defense that he believes was/is so crappy.
