Sanders is overrated the same way the ‘92-95 Cowboys are. Those teams lost games, had stalled drives, blown coverages. Accomplishment gets distorted into the illusion of perfection over time.
Sanders is a top 3 defensive player for sure. I’d probably take him first because you can do a lot on defense when you can put a guy on an island like they did with Deion. People also forget that because he played baseball he missed camp, and practice, and would still come and shut guys down. I couldn’t find the article, but I remember a story of Irvin saying in effect he didn’t think Sanders could miss all that practice and still play at such a high level, but he did.
