Some rookies made a significant impact or showed great signs of potential in 2006 and have considerable expectations heading into 2007. Vince Young, Maurice Jones-Drew, Marques Colston and Vernon Davis will all be viewed as fantasy starters heading into the new season. Yet there are some players who flew under the radar in their rookie campaigns last year and could take more steps forward in '07. Besides the bigger names -- Joseph Addai, Laurence Maroney, Matt Leinart, Jay Cutler -- here are some lesser-known, second-year players who should be monitored closely this upcoming season. Some could contribute much more than expected, and others should at least show some promise for future seasons.
Derek Hagan, WR, Miami: He should at least emerge as a quality option for the Dolphins on passing downs, and Hagan certainly has the potential to become a dependable pass-catcher. Hagan is smooth, fluid and definitely has some upside. He and Ted Ginn Jr., can be the future if the Miami receiving corps.
Demetrius Williams, WR, Baltimore: I've mentioned him before, and you'll likely see me invoke his names many more times before the season begins. Williams is big and fast, and the Ravens discovered his big-play potential late last season. It appears to be just a matter of time before he takes over a starting job for good.
