We as a fan base could go on and on about the process which out HC used and is using in determining who will go under center in any given game. That process is for the HC and his staff to develop. No matter the process, there will always be room for criticism, because that is what some fans do, no matter what.
CMD could have done what he has done, he could have decided earlier in the process, he could have started one and played him the whole game and then the next game started the other and played him the whole game. Let's face it, as long as there were going to be 2 QB's taking snaps this season, this board would have been blown up by a less than representative faction of the fan base.
CMD and the coaching staff should go about their process and not worry one bit about what the armchair coaches appearing here have to say.
