Now wait just a minute. You started this discussion by saying, "I would much rather have a qb that was always reliably good enough than one that was usually very good but occasionally missing in action." When it was pointed out to you that there's no such thing, suddenly you're changing your tune completely and saying no, you don't want a "reliably good enough" QB, you want a superman QB. If I didn't know any better, I might think that you just want to bad-mouth Dak and you'll throw anything you can come up with against the wall to try to support your argument.
Also, guess what? No QB goes "up against the best of teams and things aren't going their way" and "changes the momentum of the game by stepping up" on a regular basis. Usually, they lose those games. What do you think makes those other teams "the best of teams," anyway? The guys you're thinking of are the guys who were actually on "the best of teams" to begin with.
