Hopkins got over a 1,000 yards with no QB. He could have made a difference. Six o-line picks in two years and the Pats still had one of the worst o-lines in the NFL last year. And Zappe was just as awful as Jones. He just wasn't a head case. He was just not talented enough or could read defenses to be a decent starter.
And how do you really know that JuJu wasn't Belichick's call? He owns it either way. You cannot have final say in all personnel decisions and then say he was overruled on the moves that didn't work out. If you listen to the pro-Belichick crowd, he was forced to take Jones, he wanted to keep Meyers but was overruled, and he didn't want JuJu but listened to the analytics (even though the Patriots don't use analytics and Belichick is on the record several times saying analytics in evaluating players is bunk). I am sure that guys like Judon and Barmore were 100% Belichick's decision though.
Jones owns his failures, but stop acting like this team did what bad teams do when they ruin young QBs. Every single thing you shouldn't do with a young QB, they did.
