2. CB Chandon Sullivan
There aren't many cornerbacks around the entire NFL this year that you can argue have been much worse than Levi Wallace. However, the Steelers happen to have another CB on their own team who deserves to be thrown on the pile.
Many fans cringed when the Pittsburgh Steelers signed veteran cornerback Chandon Sullivan on Day 3 of the 2023 NFL Draft. Having watched Sullivan during his time with the Minnesota Vikings, it was clear to see that he wasn't going to be the answer at slot cornerback. In fact, some believed that he wouldn't even make the final roster in Pittsburgh this year.
Unfortunately, Sullivan has been deployed as Pittsburgh's primary nickel cornerback this year, and the results have been every bit as bad as you could imagine. The unathletic CB has been routinely toasted by faster slot receivers and he just doesn't have the coverage chops to stick with most guys in this league.
As poorly as Wallace is grading out this year, Sullivan's 41.6 overall PFF grade is even worse. This ranks him 110th among 115 qualifying cornerbacks in the NFL this year. The Steelers need to experiment with Elijah Riley or literally any other option at this point. Sullivan isn't cutting it and he shouldn't even have a job with this team in Week 8.
