A look at Colston's diminishing role

For years, Marques Colston was one of the more reliable fantasy studs in the game, but the 2013 campaign hasn't gone that way. He hasn't scored a touchdown since the New Orleans Saints' season opener and hasn't touched the 100-yard mark in '13. The past three weeks have been particularly concerning, as he has just six catches on 11 targets for 44 yards. Also telling is that he caught a pass of at least 21 yards in each of his first four games but hasn't topped 11 yards in any of his past three contests.
