Some comments on the comments:
1. Every time you want to ask a question similar to the OP, repeat this 3 times. "the first rule of capology is for every dollar you give one player there is one less dollar to give everyone else."
2. Remember that within common sense the Pats spend to the higher limits of the cap. So when you speculate if we should have kept Revis or Talib, you also have to ask who that is currently on the team would you choose to take off the team.
3. I think it should be clear by now that Revis was NEVER coming back here. The Pats gave Revis a very reasonable offer that would have made him the highest paid CB in the league.... and the Jets beat it....by a lot. The Jets would have beaten any off the Pats made, and made that clear to Revis and his people well before they were legally supposed to.
4 Talib was a more questionable decision, and in the end they decided they went as far as they could go. Talib took the top dollar from a top competitor, and has played pretty well...but after this year his cap number is going to exceed his worth not matter how well he plays.
5. I think people vastly over value how important one CB can be. Revis was even better with the Jets than he was with the Pats and he never got them past losing in the AFCCG. BB knew how to win against Revis most of the time and he was never the reason the Pats lost. He made things difficult, but look back and see all the times the Pats scored more than 30 against the Jets when they had some of the best defenses in the league including Revis.
6. People forget just how bad some of the secondaries the Pats recently had on some teams that won 12+ games, including one that went to a superbowl with 2 CB's that wouldn't make this team. BB doesn't build shut down defenses. He build D's that win games.
7. I said this earlier in the year, and I believe it more now. When the season ends, and we compare the stats between this defense and the 2014 one, the results are going to be remarkably similar, and that includes all the garbage time scores they have given up thus far ((and I count 5 TD's among those)
8. The best stat that last year's defense attained was that in the last 10 games (including the playoffs) the Pats didn't give up a SINGLE 4th quarter TD. That is a worthy goal to aspire to. Hopefully after we get through the next 4 games our defense will have improved enough to be ready to duplicate it.
