I dont see whay they would. Jamal is a great back, but hes a bulldozer type of back. In general, he hasnt show the ability to catch passes or pick up blitzes. Not because he couldnt perse, but because hes usually on the sidelines on passing downs and the Ravens have little used him out of the backfield. Also, Rhodes/Mungro and whoever else they pick up can probably handle the load just fine and with a cheaper price tag.
