I have to keep one.
I'd like to keep Henry but I hate getting involved with teams that split time with rbs. I'm leaning toward keeping Davis.
Keep Davis. He was a stud the second half of last year and won't split carries. That offense should be pretty good now that Carr has a few years experience under his belt.
I agree keep Davis. McGahee and Henry are probably both more talented but who knows who wins the job this year and beyond.
