This next offseason is going to be SO much different for Goff. Hopefully he goes back to the QB gurus he spent several weeks with last spring. It clearly helped and his footwork became so much better.
But imagine how much better he can get not having to digest a brand new offense, get acquainted with new starting WRs, etc. Pure refinement of his skills. He is not a finished product by any means- nor will he be this time next year. But he can fine tune areas in his mechanics, reads, game management, etc. and continue developing himself physically.
Much different offseason ahead for him. McVay and LaFleur must be excited to work with him further.
