I have both B.Jacobs and A.Bradshaw in my dynasty league, i am in a wait and see mode with Jacobs to see what he is going to do next season after he gets his knee worked on.
In 2008 B.Jacobs started 13 games ran for 1089 yards, averaged 5.0 YPC & 15td's, so there is still hope he can regain his 2008 form and at only 27 years old i wouldn't count Jacobs out just yet.
I wouldn't bet the farm on A.Bradshaw just yet IMO
