Harden hasn't even made his debut with this team yet, but let's suppose he and Cavs don't reach a contract extension agreement and he declines his player option.

In that hypothetical scenario, would Austin Reaves be a realistic option? Would he fit in with Mitchell, Mobley and Allen?

I'm not saying it's going to happen, but I'd like to analyze how Reaves would fit on this team.

It would be funny to contemplate a scenario where LeBron arrives in Cleveland along with AR, but that's another matter entirely.

The best option is probably keeping Harden, but could Reaves work as an alternative?
