Best answer: this is a tough call to make. personally, i''m not completely sold on Chris Johnson. i know he''s been studding, but with LenDale also having a big week last week, i see no reason why they wouldn''t continue splitting the carries fairly evenly. and with LenDale''s size, you have to give the ball to him on goalline carries. i think the Titans, as a whole, are overproducing, and i''m
