Mark Kaboly - The Steelers are going to need to keep four quarterbacks

Aaron Rodgers told Mark that this is it for him and will retire after the year. Rodgers suggested to Omar Khan that the Steelers interview Mike McCarthy. Mark thinks Drew Allar has a great arm but Will Howard has a better arm than many think. Mark would be "stunned" if Rudolph is not the backup quarterback. Mark thinks they need to keep four.
