If this were true, and not the result a noisy data set, why do you think Ya-Sin is still sitting out there in free agency? Are all 32 franchises stupid?
Dozens of reasons why. The market for DB's has been extremely soft (really chuffed we gave Jalen that early $12m deal...). Maybe he's holding out for a better offer.
Or if he's only going to sign a short deal he wasn't to be choosy about getting the right fit.
Lot's of good players still unsigned for similar reasons.
