Current 53 Man Roster after cuts before IRs and (re-)signings

How many times has the entire Saint's draft made the team?

Also, do you think coaches on the most part keep their draft pick over undrafted players to save face, even if the undrafted out play the drafted all over the field? I always think back to 2007 draft in which the Saints drafted Antonio Pittman in the 4th round, only to cut him because of a little unknown, undrafted running back out of Illinois by the name of Pierre Thomas (as I type his name, I bow to give him homage). I mean does that happen more than I realize?
