Marques Colston was being coy about how majoring in psychology at Hofstra might have given him insight into consoling a struggling teammate. Still, no one had to prod the Saints' second-year receiver to call first-round draft choice Robert Meachem after Colston noticed Meachem struggling through the opening sessions of rookie camp. "That major (psychology) doesn't help with this heat, so I just try to give him some words of encouragement because you can never have too many playmakers on your team," Colston said after an offseason training session.
