I'm probably in the minority, but I don't think the root of our problem was at QB. Alex has the tools and the weapons. This is still his make it or break it year, IMO...so I'd at least want to give him that before throwing him under the bus again.
Its a team game, even though I know the easiest thing to do is to just blame it all on the QB. Comes with the territory, but most of the INT's he's thrown this year have been to Crabs. Tipped balls and wrong routes, have more to do with Crabtree still having to play catchup, than Alex's fault.
