I have to say that as coaches these guys have to look at what these guys have been doing and what they think they are on track to do. When you see that a guy is doing poorly, but the fault rests on more than just him, then maybe it's best to let him hang in there. A change in quarterback might be able to provide a slight spark, but not necessarily ignite a fire.
For example, when you look at Brunnel, you probably think to yourself that this guy has terrible stats, he makes terribly unaccurate throws, and that it's time to try fresh new blood so that we can get out of this slump. But first, you have to look at what factors are contributing to this.
In some cases Mark Brunnel has overthrown wide open receivers, but what do we know about if the receivers are running their routes properly (perhaps running a 13 yard cross, instead of a 15 yard cross). In a game, when you have to make fast reads, these things can make a real difference. Especially when Brunnel hasn't been getting that much time as has been the case in recent games. Sometimes he basically has to find the guy and throw off his back foot. If the receivers had run consistently, then he may have made that throw (the yards that the pass looked off may have been where the receiver was supposed to be).
Brunnel may not be making all the plays and it cannot be debated that Mark hasn't been doing a lot of things right, but I think to make him shoulder the blame is kinda wrong. Most people go and they look at Ramsey going out there last year and slinging it, but you have to remember that there were some cases last year when you could see that standing by and watching could have done him a world of good. Ramsey supports and believes in Mark Brunnel...maybe some of us should too.
