I think Olave/Adams is a much better combo than Olave/Shaheed even if that is the case. Adams will almost certainly be the better option on short to intermediate routes with his route running plus contested catch ability, and if protection is an issue Carr will not always have the luxury of time to wait for Shaheed to get behind the defense.
The Saints did play more 11 personnel against the Falcons, with 28 snaps (39%). We were pass heavy in 11 personnel, passing 86% of the time (80% of the time if you exclude third down). We ran 67% of the time in all other personnel groups.
