Will Ian Book be the next Saints QB to beat out Taysom to be the starter?

I don't think you understand, what "Sean said" has nothing to do with this debate. I'm saying baring injury Trevor remains QB1 the remainder of the season. B thinks that is a moronic prediction. Last I saw, when asked about QBs by reporters, Sean says "we are going to look at everything." We will find out who QB1 will be going forward, right before the Titans.
That I can agree with, SP will evaluate the situation and modify the line-up as he sees fit. My only point was that SP did make that claim at the beginning of the season and reiterated it in the post game interview. But, he is the coach, and like a woman, can change his mind at any time (ducking out the back door).
