Turner's been in a bit of a funk, but has shown that he tends to be a TD BEAST, thus I'd rank them as did the other posters: Turner > Bradshaw > Charles > CJ
Honestly, I'd say that Charles may have more talent than Bradshaw, but his coaches don't give him nearly as much ball time as they should. Bradshaw, on the other hand, gets the monster's share of carries on his team, hence his greater value. However, if Bradshaw's health issues linger and Charles starts getting the ball more often, he could easily leapfrog Bradshaw on the list.
