No stud rookie RBs???
Jerome Bettis, Clinton Portis, Edgerrin James, LT2, Curtis Martin, Eddie George, Deuce McAllister, Eric Dickerson, Earl Campbell etc., etc., etc. were all studs as rookies. In fact, depending upon how they are used, they are the rookies most apt to be successful.
As to Jones, they seem to be working him in slowly into their system and not letting him carry the load. This seems to be Marricucci's m.o.; RBBC. What it will mean for Jones, one of the most talented rookies in this year's class, who can say at this point? I just picked up Pinner and am waiting to see what he can do.
