When Jarret Patterson left for the NFL after the 2021 season Kevin Marks became the heir apparent to the #1 spot on UB’s depth chart. For four years Marks had pushed Patterson every day for the job. At times Marks looked better than Patterson but was not the fit for the starting job that JP was.
It’s not fair to say he was backing up Patterson. While JP got more carries Marks was far more than a rotational back. Many times Marks took the offense on his shoulders and did the job just as well as JP could have.
