Dumb follows you around like cancer, one note. It never ceases to amaze me just how gullible some people are.
So let's look at the three you mentioned.
1. So we got a second for Cassell and Vrabel. That's a SECOND (top 45 pick IIRC) for a QB you no longer needed and could no longer afford. Plus getting another year in the league for Vrabel instead of just releasing him. Oh yeah, and that's a second for a guy who hadn't started as the QB on ANY team since HS prior to Brady's injury Just who was this bad for?
2. Jimmy, for what was the 33rd pick in the draft when they traded for him and wound up to be the 44th after he led them to a small winning streak. That's for a QB with 5 QUARTERS of serious game experience, when EVERY knows that you either have to trade him or let him walk as a FA. I guess you must have missed the Capitalism 101 class. Again this was bad for who?
3. Hey, they got a 2nd for a guy who was found naked and afraid outside a police station. Great one dimensional pass rusher no doubt, but when the trade was made a 2nd round pick and the former SEVENTH pick in the entire draft from the 2013 draft. It was unfortunate that Cooper had one of most injury ridden starcrossed careers one can imagine. Every time he got named to a starting role, he got hurt. Right up to 2017 when he started 13 games for the Cowboys and had a good year. Then it was back on the injury rodeo until 2019 and retirement.
Bottom line they got a good prospect and a 2nd round pick for another guy they no longer wanted and couldn't afford. It is too bad that Cooper never (except that one 13 game stretch) was never healthy, but that only makes it less good in hindsight, when ALL trades and draft picks are easy to analyze. AT THE TIME, it was universally considered more than fair. Also if you could keep only one, do you really want everyone here to believe you'd have taken Jones over Hightower?
BTW- it should also be noted that Chandler Jones played on ONE winning team in all the years he DIDN'T play on the Patriots. It doesn't mean a lot, but I've been informed that if you don't participate on winning teams, then you suck, unless of course it fits your personal narrative to use random stats anyway you choose.
