Actually, I'm pretty sure they only have 3 for the season... 1 for Fujita, 1 for Bullocks, and 1 for Simoneau.
I know things like this happen... I mean Tampa Bay has gone the entire life of their franchise and NEVER returned a KO for a TD.
I was just thinking about this last night, and I really think the last time we had a "pick 6" was when LB Keith Mitchell tipped a Jake Plummer pass to himself and took it to the house back in '00 or '01. As far as the last CB to do it for the Saints... the last one I remember is Toi Cook, circa 1992.
