Perhaps, but you don't know where the numbers will be. They could be more, they could be less. Yes, salaries have exploded but that has been driven by TV revenue. The NFL is no longer the draw it once was. Lots of fans streaming or just not watching games but instead, just watching clips. If this does not rebound, I don't know what the TV contracts do over the next few years.
I think a lot can happen around salaries. I think that if this trend continues, where you don't see mega contract QBs winning Championships, then yeah, I can definitely see QB contracts normalize. I do see that as a possible outcome but again, nothing is certain and we don't know where things will be in a few years. Could be more, could be less....
