Let me paint a picture for you.
Pete Carroll brings Canales with him to Seattle in 2010. Canales, a WR/DB as a player, coaches the WRs until 2017. Doug Baldwin, Jermaine Kearse, Sidney Rice, BMW's resurgent 2010... lot of good receivers in his time coaching them. Moves to QB coach in 2018/2019, which just happen to be two of Russell's most efficient years in his career and make him the highest paid player in the world. Moves to passing game coordinator just in time for Let Russ Cook. Moves back to focus solely on QB in 2022, and I don't have to tell you what Geno does in 2022.
Gets his first OC role under a defensive head coach, takes on playcalling duties. What does he do?
Oh, you know, just revives Baker Mayfield from the brink of career death after Baker shits it up elsewhere, including in LA under McVay.
It's Canales. You've got a guy who can maximize your bargain quarterback, develop a rookie, and has proven to be an adept playcaller. You've got a guy who has been through it all here, and proved he can do amazing away from here too. You've got a guy who'll likely mesh with Schneider.
I know they're not going to do it, but damn it, it really feels like they should.
