I believe Tomlin is a very good coach and many teams around the league - in New York, in Chicago, in Houston, in Jax - would love to have him. He's been saddled with a fading Roethlisberger the last several seasons and not much else on offense. But even with that the Steelers started 11 - 0 last season. The team is at a crossroads, one era ending and the parts not in place (i don't think Mason Rudolph is the answer at QB for instance) to start the next one. Add to this the ascendancy of the Bengals under Burrow and I think Pittsburgh is in for a couple of lean years.
Got another good to great RB. The defense is looking solid. But yeah, finding a new QB is a challenge. Steelers went the whole 80s and 90s without. There’s a reason so few coaches have won SBs with 2 different QBs, finding 1 in 1 in career is a stroke of luck, 2 is winning the lottery.
