The Nats project House to arrive in the majors the year after next. If you're confident in Abrams what's the downside of playing him at third next year. If he hits and can play third you have a young left side of the infield for the next 5 years.
I've also seen projections from this summer saying that his ETA was 2026. He's starting next year at < 20 years of age and coming off an injury that knocked out half a season. I suspect they will not push him and have him penciled in anytime before late 2024, more likely 2025. I don't think they move him off SS until 2024 at the earliest.
