I love Rice and don't like Jones relative to draft position. I got Rice in the 8th in one league and 10th in another. Jones usually goes 4th. Doesn't mean I wouldn't consider it, but I am super high on Rice this year.
I'd also keep Rice but looking at Jones' production it doesn't make sense on paper. So don't discount the offer on face value. Rice is all potential and while the sky is the limit Thomas Jones has been a brute the last two years.
