Honestly what's the harm in letting them play in playoffs? They wouldnt be the first black aces to play in the playoffs before getting much regular season time. And even with rookie Inexperience they're better than Kindl.
Might not hurt to rotate one In for a game and see how they do. I don't think it would crush their confidence if they had a bad game.
It might not crush their confidence but it might crush our chances of getting past round 1
