With the first and maybe even the second wave of free agency in the rearview mirror, the NFL of today already looks vastly different than it did a week ago. Players are set to earn millions, only to see this money disappear in roughly two years when teams realize they bought a fugazi. (In the case of Ryan Grant, this apparently took only days, instead of years.) They’ll be replaced by that season’s wave of shiny new things, and so the world turns.
