While Gregory (6-foot-5, 238 pounds) seemingly would be a great fit as an outside linebacker in the Ravens' 3-4 defense, there seemingly is zero chance Baltimore would be able to draft him unless they make a big move in the first round. In addition, while he would be a great fit, the Ravens would seem to have far bigger positional needs, such as wide receiver, running back, defensive tackle and cornerback.
The Ravens have Elvis Dumervil, Terrell Suggs and Courtney Upshaw as their top three outside 'backers. Adding someone as young and athletic as Gregory -- a guy with a high ceiling as a pass rusher -- certainly has to be tempting to Ravens decision-makers. But the cost to get into the top 10 would be steep, especially considering they can remain where they are and get a guy at a position of need who presumably could help right away.
