I don't run the 46 d can't help you there.
Barber is your trucking back, up the middle
Jones is your speed back for the edges
Jones is also an excellent return man
Jones does not catch well
Barber catches well
Choice can be subbed for either and used in the wildcat
Although Choice is an all purpose back, I don't use him much, the other two are very good
Anderson is a pretty decent fullback use him a few plays to keep em honest and he blocks well
Witten catches everything and is great with Barber in split backfield
Witten is also good in the slot
Witten catches balls thrown over and around his shoulders whether he is turned and looking or not
In the 155 defense Ratliff can hold his own with anybody in the league
