This is all absolute nonsense.
First, you complain that the situation is 'fluid', then you base your opinion on some completely delusional 'draft board' that you created out of thin air.
Second, you claim that people have flaws in their logic, then you outline a scenario in which the Bears have only 2 of the top 3 QBs on their radar, and those exact 2 QBs are the players taken before they pick at #3....do you know the odds against that happening?
Third, even if all 2 of the QBs the Bears like are drafted before they make their pick at #3, how on earth do you then draw the conclusion that "Well, we weren't able to draft one of the guys we wanted, so Mike Glennon is our franchise QB now".
Fourth, if your 'logical' scenario has all the QBs drafted before the Bears pick at #3, what point is there so saying "and then see how the draft unfolds". How many ways can it 'unfold' at that point? If you can't find a QB with the #3 overall pick, what 'unfolding' needs to be done? Are the Bears going to be like "we really wanted Peterman in the 5th round, but the Niners grabbed him before we could draft him". It makes no sense. The Bears control their own destiny.
