1) Vacarro a solid first round choice? He was benched at some point last season due to horrible play. He definitely has the potential to be a good safety, but so far that pick hasn't worked out completely for the Saints.
2) Stanley Jean-Baptiste has intriguing size, yes. But a 2nd round-CB that only ends up playing eight snaps in his rookie year (no injury) for a team with secondary issues is not promising.
3) When mentioning Fortt as "promising" you're shooting yourself in the foot. He was waived by the Saints early in the season, and as far as I know, he's already on his third team in the NFL.
