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

Nothing he posted was an opinion, it was factual. SP did actually say all that. Now, whether or not he adheres to it for the remainder of the season is another question.
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.
