I'm still confused on how it's overrated. The odds of us scoring before halftime with the remaining time left went up immensely after that blocked punt. They did their job. Brady made a rare mental mistake and it cost us. That doesn't lower the value of special teams though. The overwhelming majority of the time, that's an automatic 3 points on the board, and a lot of times 7. Special teams gave them that opportunity. It's like saying having a great long snapper and a holder that always places the ball perfectly is overrated because sometimes the kicker misses it anyway. Well, he'd miss more often if those other guys were worse at their job.
Look at it this way: if we blocked 2 punts deep in our opponent's territory in 100 straight games, how often do we lose? You can't overrate their performance by looking at what is certainly a very rare outcome.
