You're right. However, the one thing all of the successful rookies have in common is a HC/OC that either trims the playbook and expands it as the rookie QB becomes comfortable or simplifies the play calling or SOMETHING to help the rookie acclimate.
Fisher won't do that. He's just that old school. He expects the rookie to get fully up to the level in all aspects of the Vet before displacing him.
That is why Fisher has such an issue getting rookies at certain positions to contribute.
Would Pederson be rocking and rolling with Goff? I dunno, but I think it's certainly reasonable to believe that he'd have found a way to have him ready to be productive.
Wentz, Prescott and Brissett, even, have been productive because of functioning schemes and staffs that are committed to seeing them succeed.
The frustrating part for all of us fans on all sides of the QB debate is that we don't know if we got Aaron Rodgers, Alex Smith...or Matt Barkley. Moreover, it really didn't help that all of the hype COMPLETELY ignored the reality that is Jeff Fisher...which we've seen play out.
1) Goff not only didn't start, but he started out as the 3rd string QB and didn't even dress.
2) The offense, including the nightmarish play_calling nomenclature wasn't simplified in order to both improve game/clock management and to more quickly transition the Xs and Os to the field.
3) There is still no clear rep allocation for the QBs beyond getting the starter ready to play (and not every practice is open) so we don't know how much either young QB is getting actual reps with which string.
Thus, while the hype for Goff may, in the abstract, be totally warranted, it's more than a little frustrating that no one can say what we have in young Goff.
The hype is gone for now because...well, it's football season and hype means nothing and it's all about the scoreboard. Which leaves us Rams fans with??? the reality of Fisher.
I'd love to think that the shackles on this scheme are all a function of the limitations of Keenum, but then what explains the first few years?
Essentially, it seems like Fisher's belligerence is holding Goff back because he has more faith in "his way" than he's committed to getting Goff productive....now. I suppose it's possible that Goff is just that far behind, but it almost seems like they're trying to make him seem lost. And I find it hard to believe that he's THAT far behind.
