Right, but I guess that's my point. If the barometer is "better than Snead at receiver", then I'd be targeting somebody in that price range that's younger, or I'd be targeting somebody in a higher price range. They're still going to want receivers who can block.
Plus, I wouldn't really be interested in signing Sanders for more than a one year contract. They'll give him guaranteed money for year 1, which means if you backload it, he'll have some dead money in 2022.
I think it will be hard to sign anybody to a one year contract for much more than the vet minimum. I think anybody we sign we should sign with the intention of being here for multiple years, otherwise our dead money in 2022 is just going to continue to climb. And while 2022's cap MIGHT be considerably higher (we're all assuming fans are back in the stands in the Fall, which I don't believe is a guarantee) than 2021, the last thing I'd want to be doing is spending the delta on dead money because we signed veterans we only ever wanted for one year to multi-year deals.
