There's been plenty of negative things said about Martz. Here's what Dick Vermeil had to say about him: "I can't think, in my history of coaching, of any assistant who came into an NFL franchise and made the immediate impact that Mike Martz did." As for Lovie and Martz not working well together, it might be correct, but I think Lovie is content to leave the offense alone. This wouldn't be like bringing in a caustic DC where Lovie would be clashing horns over what defenses to run. Lovie doesn't know offense. He would be essentially turning the offensive side of the ball over to Martz, just like he did with Ron Turner. And I think that's the way Martz would like to work. So I believe there's also potential for it working out fine. ...and I'm completely and totally convinced that Martz is a big upgrade over Turner.
