The true picture or an anomaly ? ( Derek Carr)

Do you guys think the Derek Carr we saw the last 4 weeks of the season is a more accurate of an assessment of his ability or the first 13 weeks. In other words do you guys think with the right OC and a better line can expect more of a complete and better qb or is that pie in the sky thinking?
Carr will never be what Brees or Brady were or even what Mahomes is. That being said he’s a better QB than what was shown first 12 weeks or so. Also credit to his toughness he played hurt a or of the season thanks to this o line. With a better line and better play calling and an added weapon or two I think you see way more of the latter Carr than the earlier or even slightly better.
