Your case is not that compelling.
This got me thinking and I got bored, so let's look at the different categories of QBs as of now and how they ended up starting.
Drafted and started as rookies right away for their respective teams (ie expected to be the guy as most were very high picks):
Rg3
Big Ben
Tannehill
Newton
Winston
Bridgewater and for the current QB there..... Bradford as well
Flacco
Dalton
Bortles
Mariota
Wentz
Carr
Stafford
Ryan
Gabbert
Palmer
Wilson
Luck
Guys drafted as backups with no intention/expectation to ever be the starter:
Cousins: drafter the same year as Rg3 in the 4th round, but not expected to be a starter so he sat
Osweiler: Drafted during Tebowmania
Tyrod Taylor: drafted as a backup...Ravens already had Flacco
Fitzpatrick: 7th round pick who wasnt expected to even make a roster, so he sat because of that. He rode the pine for years as a perennial backup.
Tony Romo: Undrafted pickup for the Cowboys....turned out like Brady to a much lesser extent to be a diamond in the rough who also replaced Drew Bledsoe (that poor fuck)
Brady: drafted late in the draft with no intention of replacing Drew Bledsoe who was the guy in NE...we know how this all played out (luckiest shit ever)
Siemians: 7th round pick from last year, for now the starter...drafted on a team with Manning and Osweiler. Still expecting Lynch to be the starter this year at some point....too early to tell really on this one.
Guys drafted to eventually be the starter, but drafted to teams with an established good/great QB
Rodgers: Favre etc. Truly the rarest outlier here next to lucking into Brady.
Prescott: drafted as a backup, started due to injury. Drafted as Romo's eventual replacement
Eli Manning: Held a clipboard his first year behind Kurt Warner.....still started something like 7 games after Warner fumbled like 12 times a game in NY.
Guys who were drafted and expected to start eventually, who actually sat a good amount their rookie years (ie drafted very high but still sat)
Philip Rivers: drafted 4th overall and sat behind Drew Brees...who SD apparently had no clue was as good as he was....
Alex Smith: started 7 games his rookie year, but still sat for part of the season behind shitty QBs so he can count for this.
Goff: All the QBs suck on this team, why he is sitting is beyond me...still its Fisher doing Fisher things
Lynch: I'm assuming he goes here? He got beat out by a 7th round pick from last year....but assuming he will be the guy one day though? So for argument's sake let's count him for now b/c Denver likes to do this
Brees: sat in SD for 1 year behind Flutie team that was 1-15. Wasnt a super high pick, not sure if they expected him to be the "guy"...they drafted Rivers not long after. Makes as much sense as firing your HC who went 14-2. Idk....just San Diego things.
Cutler: That was a weird saga with Jake Plummer and his disappearance from football, but he sat most of the year.....again Denver.
Definitely seems that some teams like to sit QBs more than others: SD and Denver account for over half of the QBs who sat their 1st year but were drafted with the need of a QB right away and expected to be the guy. The rest of the league were either guys who were drafted and expected to start who did start right away as rookies (vast majority),or were hidden gems who were never expected to amount to shit but turned out to be good or even great QBs.
What's all this mean? Very few guys actually do sit on teams with bad QBs. Many of the good ones who sat did so behind good QBs, so it makes sense there because there was no need to start them right away. But to bring this thing full circle, Goff is not in that situation though.
