Swift/Mitchell workloads

I have R. Jones and Wilson. I need a RB for the championship game. I think both Swift and Mitchell will be available but I’m concerned about workloads. Does anyone have any info on these two guys

Jones is a must-start against the Jets and Swift is a must-start against Seattle.

Hard to say with Mitchell, so probably best to avoid San Fran this week, unless you need a third RB.
