No. Brady's promise didn't become apparent 'til his second training camp, he threw only three passes his rookie year. Conversely, Mac looked good his rookie season then faltered under Patricia/Judge. BB brought in BOB hoping Mac could pick up where he left off in 2021. It didn't work out because BB the GM botched the offensive roster which became further hampered by injury, while Mac ultimately proved he couldn't be a difference maker.
Again, Mac was a first-round pick -- a significant investment whose franchise value had to be determined. None of this suggests meddling by Kraft, an avowed hands-off owner who has publicly endorsed BB's autonomy re. football operations on many occasions.
