Considering the Ravens’ recent history, at least one man from their 2009 crop of rookie free agents will make the active roster.Linebacker Jameel McClain is looking to see a more active role on the defense, and he went undrafted last season. So did tight end Edgar Jones in 2007. There has also been linebacker Bart Scott, safety Will Demps and center Mike Flynn in the past. Defensive back K.J. Gerard is making a strong bid to take that title this year.
