There were so many things working against Mac that Belichick created. The o-line was a disaster the last two years with last year being worse than the year before. The Pats had no weapons for him to throw to. Belichick fueled the fire of a QB controversy in 2022 rather than doing what a good head coach does and squelches it even if his starting QB is really on thin ice and in danger of being pulled. Every expert mocked the Patricia offense for being too simple with poor route running and with no one seeming to know where they are supposed to go. The Patricia/Judge thing was a disaster. One of the biggest under the radar issues was getting rid of Hoyer based on a bogus injury because he questioned Patricia's offense. Not ever giving him a 3rd down back which was so key during the Brady era (Faulk, White, Vereen, Lewis, Woodhead, etc.). I could go on with the tings.
I cannot think of a single QB over the last two years who had a worse situation than Mac Jones. Many unbiased observers agree.
I admit he did not handle the adversity the way a starting QB should. In fact, he handled it horribly at times. That makes him untrustworthy because you have to trust your QB to be as cool as ice in the most pressure situations. But to dismiss how the Patriots did everything possible to ruin this guy like most bad teams do is ridiculous.
