Versatile Roberts leads midround WR sleepers 
New Orleans Saints WR Marques Colston posted good numbers in college and turned some heads at the 2006 East-West Shrine Game, but there were enough questions to make him a fringe draft pick coming out of Hofstra.
An average 40-yard dash time at the combine and a lack of burst out of cuts intensified concerns about the competition he faced at the Division I-AA/FCS level, and missing the entire 2004 season with a shoulder injury was also a significant strike against Colston.
The Saints decided to take him in the seventh (and final) round of the 2006 draft, with the 252nd pick, and he's played a big role in their becoming Super Bowl champions. While injuries have been an issue at times, he's finished with at least 1,000 yards receiving in three of his four seasons and led the Saints in receiving (seven catches for 83 yards) in their Super Bowl XLIV victory over the Indianapolis Colts.
Below is a look at three players we feel could offer similar values in the mid-to-late rounds and why we think they could become contributors the way Colston has.
To see which receivers Scouts Inc. feels will offer the biggest potential value in the middle rounds, you must be an ESPN Insider.
