The children who want to slam the door on Rosen are just pouting / ranting because he didn't play at an executive level at 22-years-old behind an absolutely dysfunctional OL with ZERO run game support to complement his efforts.
I saw more than enough from Rosen in terms of pocket awareness, live arm, quick release and mobility to justify a much deeper (and longer) "evaluation" and subsequent coaching.
HE IS NOT TRASH! And the kid was thrown into just about the worst possible scenario to "prove" his chops and -- effectively forced to carry the team like a high-performance vet! It's just ridiculous to formulate a final judgment based on the circumstances he was subjected to.
Last, however good or bad Rosen's NFL career is going to be his projected success or failure rate is comparable to the shiny new QB objects available in the '20 draft! And counter to what others have said regarding Flores opinion on Rosen -- Flo was highly complimentary of Rosen's work and development throughout the season behind the scenes.
I just don't get how anyone can be a fan of the TEAM and not root for the kids development and hope that he is the answer @QB. And with that in mind -- realize he's super young with a lot of positive tools to work with -- IF ??? we surround him with a complimentary system and players.
And if he'd played well, the narrative would be 'just think how much better the team would be with Tua.' Agendas distort reality.
