I am a HUGE R.Rice supporter this year but I still feel as you would be overpaying here!
I think Jacobs is strong and injury free this year (lol.....one of the few) so I think Jacobs will run circles on Rice for fantasy STATS. CJ is a good upgrade over Roy but not much as people are saying!
Stick with what you have!
