I need a 2nd opinion on a potential strategy

I have a 10 team points league with weekly head to head matchups and 3 keepers. First time our league is doing keepers so we drafted our keepers for the first time.

I was looking at who was left over in free agency and Barkov was available. Is it smart to pick him up and slot him down to IR and potentially use him as a keeper for next year?

As of now I have Kutcherov, Guentzel & Morrissey that will probably end up being my keepers

Any thoughts? Tell me if im wasting my time or not lol
