I can't tell if you are truly missing the point or just pretending to.
What was Brady's arm strength coming from a college powerhouse? Mac Jones level, I would think.
Armstrength? You mean like Jamarcus Russel (Josh was his comp by Mayockin 2018)?
JA was pretty bad his rookie year. His arm strength hasn't made him a steadily better player (many argue hear he often throws the ball too hard too often).
Anyway, it's hard to fathom BB would, after a season, think to dump a kid with relatively little starting experience in college who led the team to 10 wins, was 13th in yards, 8th in completion % after a season.
That makes little sense. Don't you agree?
