ah gotcha...that's a totally loaded question.
Ive thought of that same question (as well as many other similar scenario's us Pats Fans like to torture ourselves with)
I think a lot of is cultural with the organizations "manifesto" over the last two decades. we have had so much success that we like to attribute and engrain that to our culture, the "patriots way".
Our heros have typically been the unheralded non blue chip player (brady, edelman, even gronk). we dont make splashes in big names etc (we have). so we've gotten used to the the you may be stronger but we're smarter and we can do more with less. we feel entitled when the player gets bigger than the organization, we turn on players that leave (im guiltily too, F welker) and want to sustain the principle that the organization has been the key over any player.
so when we knew Brady was at the "end" (or so we thought), we wanted Jimmy...now we want Stidham. We don't want to rely on a player to come in and save us (unless its AB)
i dont know..that my best guess on why we (some of us) convince ourselves Stidham is the new Goat, F Brady, etc.
im team brady, im hoping Cam goes wild and of course, 100% GO PATS.
