One thing that's changed under Tomlin is the Steelers have become a team of mercenaries, especially at the offensive skill positions.
Rodgers
Metcalf, Thielen, Valdez-Scantling
Gainwell
Jonnu Smith
Meanwhile, this year's 3rd round RB is in the doghouse. Last year's 3rd round WR is in the doghouse. They gave up on their 2022 2nd round WR. Their 2022 4th round WR gets about two targets a game. Their 2021 2nd round TE has been passed on the depth chart by a 311-pound TE that Rodgers prefers. And their 2022 1st round QB is trying to latch onto his fourth team.
Also throw in that most of their secondary was not home grown: Clark, Dugger, Echols, Peppers, Ramsey and Samuels are all from other teams. Castro and Pierre were UDFAs. Only Porter Jr. was a Steelers draft pick. That's weird because Tomlin made his first real impression in coaching as a DB coach. One would think he would be good at coaching up that position instead of relying on so many established veterans.
They have plenty of drafted offensive linemen but that unit is leading the team to a 29th ranking in rushing.
They have for the most part good players at DL and Edge/LB, but their best defensive lineman was drafted 14 years ago.
For decades the Steelers prided themselves on the drafting ability and developing talent from within. For many positions those days appear to be gone.
