Crazy as it sounds, I think there's a chance the Steelers could win the super bowl this year.
The defense is super bowl caliber barring injury. The pass rush will be one of the best. The secondary should be improved. Half a year of Cam Sutton is a major upgrade at nickel. ILB was upgraded last year but were decimated by injury. Now with Queen and Wilson they should have the best ILbs they've had since Shazier.
It's all about the offense. How can this offense be good enough to win the super bowl?
The OL comes together quickly. Not immediately, but they are playing "above the line" by week 4 or 5 and then by week 12 or so they are one of the better OL in the league. If this happens, it opens up everything. Defense keeps games close, the OL paves the way for a physical and dominating run game, and the play action pass opens up.
Somebody steps up as #2 WR. I think Freiermuth may be the #2 target but they still need a WR to step up and be a 3rd target.
Wilson or Fields executes the offense without excessive freelancing. Smith's offense is all about having a strong run game, that sets up play action passes that are cleverly disguised. Canada's main problem was his offense hid nothing. Defenses could read it like book. Smith's offense is simple but to the defense everything looks the same. It has no tells, or very few.
This offense does not need a great QB. It just needs one with some athleticism for the play fakes and accuracy to get run after catch. Another thing Canada's offense lacked.
Wilson struggled in Sean Payton's offense. That offense wants a QB to make very fast reads from the pocket. Wilson's not great at that. He likes to be on the move. Smith's offense plays to Wilson's strengths.
I also happen to think the Steelers will make a splash move on offense to bring in a WR.
Dominant defense, plus a top run game, plus a competent play action passing game if pretty much how the 49ers have won so many games. The Steelers may have the pieces to do similar.
