Chris Carter, NFL and NCAAF analyst, hosts the Locked on Steelers podcast and is joined by Tony Serino of the AFC North Talk show.Ahkello Witherspoon spoke with Pittsburgh media Monday and looks to be the Steelers' biggest free agency add to the cornerback room. But is that the last addition at cornerback this offseason? Currently the top cornerbacks would be Witherspoon, Cam Sutton, Levi Wallace, Arthur Maulet, James Pierre and Justin Layne. None of those players are guaranteed CB1 options for a defense that wants to be an elite group in 2022, so does that mean another addition has to be coming?The addition of a player like Stephon Gilmore is highly unlikely and Ahmad "Sauce" Gardner most likely gets picked very high in the NFL Draft. But both LSU's Derek Stingley Jr. and Clemson's Andrew Booth Jr. could be players who slip to the Steelers' 20th overall pick. If that happens, do Mike Tomlin and Kevin Colbert make the move to add them at cornerback? Doing so would give the Steelers a potential cornerback star for the future and would be the highest graded prospect at cornerback to come to the team in the draft in decades.Meanwhile, the Steelers have signed Genard Avery to help with the edge rusher group. What does the former Philadelphia Eagles and Cleveland Browns linebacker bring to the table? A really athletic skill set to back up T.J. Watt and Alex Highsmith. But is that enough? Taco Charlton should still be on a call list for the Steelers to complete the edge rusher depth group.Finally, after Colbert and Matt Canada visited the North Carolina Pro Day to see Sam Howell, the Steelers have made the rounds to all the NFL Draft's top quarterbacks. But does that lock them into picking a quarterback in the first round?Follow Chris Carter on Twitter: @CarterCritiques.Theme music is 'Soul Kick' by Ceddy P, and 'Too Easy' by Nerdboy.
