The homer view is that Boller is a super hyper mistake prone QB who you can't win the big game with. The homer view is that sooner or later, Boller will stumble, bumble, fumble his way into failure.
Boller is viewed as Billick's boy. As I wrote earlier, on the local talk shows, if a player is a good pickup it's because of Ozzie, and if they are a bust, it's all Billick.
McNair is viewed as a calming presence for the offense. McNair isn't going to put up big numbers, but there were several games last year that "we" won that we wouldn't have without him -- Tennessee, Cleveland, etc.
Personally, I root for Boller to do well simply because he is so hated. And he is tough, both mentally and physically. To this non-educated observer, it doesn't always seem that he has a great feel for the game. He also has issues with accuracy. He has gotten much better over the last few years, and I do thing sitting and watching has helped him.
It's interesting that the Ravens resigned him to a 1 year deal and made no efforts at signing Culpepper/Leftwich. They (meaning Ozzie) must have some faith in him, as they had every opportunity to cut their losses.
I think the National view of McNair is based off the horrible playoff loss to the Colts, and MNF vs Cincy. He hurt his groin early on in that game and most of his passes were high and off the mark. It will be interesting to see how he looks in the coming weeks.
It seems like the Ravens want to go to a more wide open attack with three wides, but IMHO, it would be more like the Run and Dink, as McNair doesn't have the arm to get it downfield in on a consistant basis.
I do not think McNair losses the job this year unless the season totally goes into the toliet. I DO have my doubts that he will last the season physically.
