Stash Henry for a 1st or Dobbins or a 14th?

My league allows 1 keeper, you keep them in the same round you drafted them the previous year. We have an IR slot, so I drafted Dobbins in the 14th w/ the intention of possibly stashing him in my IR slot all year and having him as a keeper in the 14th rd. next year. Now that Henry is (likely) out for the year, who is a better use of my IR slot for next year keeper purposes?

Henry in the 1st (likely 5-10 overall), or Dobbins in the 14th?

I’d go Dobbins strictly out of value gained.

You don’t gain any value from Henry and could theoretically draft him at his position.
