The Super Bowl played out Sunday night, and with it, the end of the 2018 season. There is still some time to wait out for some things -- the new league year doesn't begin until March 13 -- but Monday, one of the benefits the Cardinals get from suffering through such an awful season kicked in. The waiver system for 2019 started, and the Cardinals find themselves at the top of the waiver claim list.
Waiver claims work as such: Players with less than four accrued seasons who are released are subject to waivers -- meaning any team that is willing to take that player's contract as is can claim the player. The Cardinals, who own the top draft pick because of their record, also own the top waiver claim slot. That means they will have first shot at any player available on waivers, all the way through the first month of the season.
That may not mean a ton right now, since teams have 90-man rosters and there is little reason to release anyone right now who are talented (Older players who are cut, with at least four accrued seasons, become unrestricted free agents if they are released.) But come training camp, or more importantly, during final cuts in early September, waivers can absolutely be a way for the Cards to build the bottom part of the roster.
The Cards grabbed a few players off waivers last year, including a few offensive linemen, wide receiver Pharoh Cooper and safety D.J. Swearinger (the latter of whom was a vet, but in the last part of the regular season, even the 4-plus season vets are subject to waivers). No team wants to be in a position to have the first waiver claim, but if it is the case, might as well make it work.
