NEW ORLEANS (AP) — New Orleans Saints coach Sean Payton couldn't resist trying out another former college basketball player at tight end. Who could blame him after the smashing success Jimmy Graham became before New Orleans traded him and his hefty contract to Seattle? Unlike Graham, who played one season of college football at Miami before entering the NFL draft, Manhertz never played football at any level, or even watched it on TV that much growing up. [...] Manhertz, who signed with New Orleans this week, suspects that if any NFL coaching staff can help him make the transition to pro football, it's Payton's. Given how scouting has evolved with technology, Payton said he wasn't surprised to see an NFL team approach a non-football player about trying out, rather than the other way around.
