Jones was "tossed" because he wouldn't talk to the Patriots about a new contract. Heck, he wouldn't do a deal with his new team, the Cardinals, either. They had to apply the Franchise tag, which stayed in place until he signed that huge contract.
The year he got that huge contract, the Patriots had several players needing a new deal. They could never have fit Jones' huge contract onto their cap and been able to have the roster that won 2 more Super Bowls.
Whataboutism goes both ways. During the 4 years after Jones left, the Patriots went 14-2, 13-3, 11-5 and 12-4 with 3 trips to the Super Bowl, winning 2 of them. The Cardinals went 7-8, 8-8, 3-13 & 5-10 and failed to make the playoffs. And remember, the year before they traded for Jones, they were in the NFC championship game after going 13-3. When you complain about that trade, look at the results in the standings and just be happy with those results.
It's simple, the Patriots were a better team without Jones than the Cardinals were with him.
