Because Stevens is not Tom Thibideau and won't run his players into the ground.
So any time Stevens makes a decision that Mr. October, OP, and others who view it as sub-optimal its going to be sneaky tanking?
Same thing for the thought that playing Olynyk and Faverani together is "sneaky tanking". Your starting C and backup PF overlapped in minutes, that happens with most teams. Plus do you think having the backup C (Humphries) would have made life much easier for Olynyk?
I mean of our big man rotation 3/5 of it is raw Sullinger/Olynyk/Faverani. So the young guys are going to be playing together for long stretches no matter what, plus its not like Bass/Humphries are defensive anchors themselves.
