Systems are only "outdated" but we have more athletes than can throw than QBs...lol. That system won 7 Super Bowls, with the last being in 2020 (IYKYK). Modern offenses are really those that require less of the QB, but that's another conversation.
In terms of Mac Jones, this actually matters. The 2022 Patriots would have been better, as opposed to what we saw with the Joe Judge/Matt Patricia Power Team. Which goes back to the point that Josh McDaniels is a great offensive coordinator. Dismissing what he has done because he has worked with Brady most of his career makes no sense, especially with him having success outside of Brady. His issue was never X&Os; his issue is he comes from the Bill Belichick coaching tree, which saw one of the greatest QBs in the NFL get chewed out in front of the entire team like he was a scrub and who asked to be coached hard. That doesn't fly in most places, especially in today's NFL.
