A metric I haven't seen tracked anywhere, but have found interesting to look at, is the combined cap hit of the QB and the LT. Alternatively, the combined cap hit of the QB and both tackles.
I've found some interesting patterns, but nothing interesting enough to make a full post on.
I do think there is an optimal combined cap hit for team success. A sweet spot between too cheap giving you not enough production from the offense, and too expensive when you reach a point of diminishing returns.
If you are paying top dollar to a QB, you will need to go cheap at the tackle spots to optimize your offense. If you have a rookie QB, your optimal offense will include a highly paid tackle or two.
Buy then you have the true outliers that screw up the narrative. The Seahawks have a cheap QB playing at an elite level. They also have rookie contract tackles playing at an elite level. That leaves us so much cap space to spend elsewhere, but it isn't a reproducible formula.
I was thinking about this too, that Pete's SB48 winning formula was:
* Cheap-but-very-good QB with a great deep ball
* Cheap road grader run game O-Line
* Elite tough-yards RB who forces opponents to stack the box
* Pedestrian cheap receivers who walk their ass to the Super Bowl
* Spending the big money mostly on the D side of the ball
* An elite defense with several key free-agent signings who took cheap deals
* A dangerous and effective pass rush (Avril, Bennett, other effective rotational rushers)
* A DL rotation that keeps fresh, good DTs and DEs on the field
* Young-and-good corners
* Bobby Wagner in the middle running the D
It seems Pete and the Seahawks have a lot of the pieces for Pete's "winning formula" in place for the upcoming season. To properly complete this, in the draft or free agency, Hawks need to pick up:
DT/DE good rotational pieces (Arguing for Jalen Carter at #5 or trade down and take him, plus snag Siaki Ika)
LB (Will Anderson Jr. if falls to Seattle)
IOL (Peter Skoronski and use him at G)
RB (Surprise trade-down pick: Bijan Robinson; more likely, a mid-round 210+ pounder)
OK, so those are blue-sky wishlist picks, we won't get more than 1 or 2, and I suspect the truth of how this draft unfolds could wind up being stranger than fiction. If Seattle hits on the 1st and 2nd rounders and scores some mid-round and late-round gems, this could rank up there as an all-time best Seahawks draft, and create a playoff success window of multiple years.
