The bad part in all of this for Boston is the fact the Saints probably knew what they were going to do after Peat exited the game Thursday night in the first half and headed to the lockerroom. By waiting to release Boston until well into game week they increased their chances he would clear waivers and they could add him to their practice squad.
The Saints knew Peat's injury from last year's playoffs might take this long to heal. They then passed on matching the money the Texans gave Senio Kelemente to be a starter, signed Jermon Bushrod as a backup tackle, where he hasn't played in 4 years (he's played guard the past 3 seasons), and then drafted a project in tackle Rick Leonard from Florida State, who is the highest draft pick the Saints have waived in the final 53-man cuts since 2010.
That's led them to having to sign two backup tackles with Peat questionable. Boston then gets caught in the numbers game.
