I think Chris will do a lot better than 1100 yards.
Eddie George got just over 1000 yards last yr whilst averaging 3.3 ypc.
Brown has looked excellent in preseason. If Brown gets as many carries as George did last yr, and theres no reason to believe he wont, and he averages around 4.5 ypc, then hell top 1400 yards.
I dont think 1400 and around 10TD is being too unrealistic.
