Getting a viable QB is also a really big deal.
It doesn't matter whether you or I think they are a QB away. All that matters is are they interested in getting a veteran QB. If we can project they will be interested come next spring, why wouldn't they be interested today?? In other words, I don't accept that teams will be beating down the door .... but no one could be enticed to act now. As you said, procrastination.
Because several of them have the money & capital to drastically change their roster in a short period of time.
