The quarterback questions that have dominated Steelers training camp will soon be answered. Friday’s preseason game in Buffalo is expected to feature a heavy dose of Will Howard and Drew Allar. By 6 p.m. ET on Sunday, the 53-man roster is due and the final decision will be official.How many quarterbacks will the Steelers keep, and how will they be ordered on the depth chart? Coach Mike McCarthy, publicly at least, said that the decision has not yet been made. However, when asked on Tuesday if he could find enough reps for four quarterbacks — Aaron Rodgers, Mason Rudolph, Howard and Allar — McCarthy appeared more than open to this possibility.“I don’t think it would hinder (the opportunity to develop) at all,” McCarthy said. “We’ve talked extensively about the importance of the whole quarterback room. If you have four quarterbacks in that room, especially the quality that we have currently, I think it only enhances what the regular season would look like.”Joey Porter Jr. and Steelers at an 'impasse' on contract talksMike DeFaboMcCarthy said that there are fewer time restrictions during the season under the CBA. In that way, he’d be able to do more with his QB School before and after practice than he’s permitted to currently.“I’d have six quarterbacks in the building if it worked,” he said.As the time nears to make the decision final, let’s take a look at the arguments for and against keeping four quarterbacks on the 53-man roster.The case for 4 QBsShifting priorities toward the most important position: The Steelers’ inability to identify, draft and develop Ben Roethlisberger’s successor is a significant reason why the team hasn’t won a playoff game in almost a decade, why coach Mike Tomlin resigned and why the team pivoted from its defense-first model to hire an offensive-minded head coach in McCarthy. If the quarterback position was one of the main reasons the Steelers chose McCarthy, it would make sense to surround him with as many moldable pieces as possible.A backup quarterback for now — and two for the future: Rather than turning over the roster when McCarthy was hired, the Steelers remained committed to the current window by keeping aging veterans such as T.J. Watt, extending 37-year-old Cameron Heyward, trading for a 28-year-old Michael Pittman Jr., adding a 29-year-old Jamel Dean and — more than anything else — waiting for a 42-year-old Rodgers. If the Steelers are going to put themselves in this win-now posture, Rudolph gives them the best chance to step in and win a game or two if Rodgers goes down with an injury. Carrying two young QB who have never appeared in an NFL regular season game behind a 42-year-old QB would be a risk.Organizational belief in development: When the Steelers drafted Rudolph in 2018, they didn’t even employ a quarterbacks coach. Under McCarthy, the approach to QB development couldn’t be more different than what Rudolph went through. With his QB School, McCarthy is, arguably, the most hands-on head coach in the league when it comes to drilling the fundamentals. When you add in OC Brian Angelichio, QBs coach Tom Arth (who went through the QB school himself) and Rodgers, the Steelers have created an ideal environment for a young passer to learn.Rodgers factor: Rodgers has proven himself to be a willing mentor from the moment he walked into the building a year ago. Allar talked about how the future Hall of Fame QB has given him “cheat codes” to beat certain coverages. Howard has discussed how Rodgers has helped him understand defenses on a much deeper level. In virtually every practice, Rodgers is giving the young quarterbacks some small piece of information — how to throw the ball on the run, how to carry out play-action, how to manipulate defenders with their eyes. Keeping both QBs would give them both the opportunity to learn all that Rodgers has to offer.Setting the stage for 2027: The Steelers did everything in their power to put themselves in position to land a first-round quarterback in 2026, stockpiling a league-high 12 draft picks. However, when a once-promising QB class underperformed, it left the Steelers taking a chance in the middle rounds. So while it’s easy to say that right now the Steelers’ answer at QB can be found in the early rounds of the 2027 draft, what if they’re in the same situation as last year? Rodgers is likely to play well enough to keep the Steelers from picking early enough to get one of the top passers. By keeping Howard and Allar, the Steelers can develop the two young QBs this year and then have them compete for the starting job in 2027.
