Webb hasn't even taken a snap at the NFL level. Geno can play and he knows the book.
And again, I'll ask to what purpose?
We stink. Geno isn't going to play any better then Eli did against Philly and TB, so you're going to bench your franchise's GOAT QB, end his streak and guarantee permanently severed ties with him, for a guy that will lose just the same, with no importance or potential importance to the team beyond this already established as trash year?
Like I said, they're not benching Manning, but if they were to even consider it, at least Webb will still be here as a backup for three more years and they could take the gamble on him flashing more than that. If he's garbage, it wouldn't matter because they really shouldn't be winning games anyway now.
