Reading the blurbs about Trestman's career(thanks Red Air Force) he may be a pretty good choice for the Raiders. I don't really know anything about him or what he's all about but the couple of times I watched the Raiders this year, their defense wasn't really their problem. Ryan might actually have a decent unit for them to rely on.
I've mentioned that I think Martz might be a good fit in Arizona in '07, but I've got this feeling that he'll be the guy in Oakland when all is said and done. He's a maverick, Big Al loves offense and scoring points and Martz, as mucch as some people don't like him, has a way of getting the most out of his qb's. Right now, that's what Oakland really needs is to settle on and develop a qb. Yes, their o-line needs a lot of work too but the qb carousel will keep the team in dissaray just as much or more than anything else on offense.
On top of that, hiring Martz would give the Raiders quite a bit of publicity. Moss and Martz on the same team would be a car wreck that would be hard not to watch. Davis tried the respectable, honorable, sentimental choice in rehiring Shell but that team needs a spark. The excitement that would come from Martz being there just might get Randy motivated(remember, Isaac Bruce wasn't particularly happy or productive for the Rams in '97 & '98) and get the rest of the team playing with some confidence. Of course, it could all blow up too.
