Hey, we're all experts here.
I don't necessarily think that 5 qbs will be picked, mostly because I don't think anyone is going to trade up for Davis Webb who is, no matter what the bullshit chatter says, is a huge drop in talent from Kizer. There are teams purposely dissing Kizer so he will drop and some of the stuff you read from "anonymous scouts" are reacting to stuff in the media like some of the knee-jerk folks here do without ever having talked to Kizer or knowing the full context of what he said.
There are always a bunch of smoke screens laid out during the draft for various reasons. For example, the teams that aren't going to take a player early like other teams to think they might giving them a chance to a) move down or b) get that player picked ahead of them enabling more players they like to fall. I don't really think the Jets or Bills will take a qb at their current spots in the 1st round but they want to Browns to think they might. The Bears aren't going to take Fournette but they want the Jags and Carolina to think they might.
Much worse qbs than Kizer have been taken in the 1st round.
