Teams with a small amount of mentors tend to have a low OPR.
Teams with a small amount of mentors tend to be victims of attrition.
Teams with low OPR tend to be victims of attrition.

Solution: Let's fix the OPR problem by allowing teams more plays and/or unbag time.

Possible result: already thin-stretched mentors get more burnout faster, and the attrition actually increases as fringe teams fall away.*

OPR is a symptom, not the disease.

Perhaps this is an example of a conflation of symptoms at which gblake and others have been hinting.

(And the small number of mentors example is one of a myriad of possible challenges teams face. Please don't take my example as a one-and-only offering.)
(Also please don't take this as an opinion of my being pro- or anti-SBD. I honestly don't know where I stand yet.)

*Paradoxically, by dropping some of the low-performing teams, the 'product' will get better and more media friendly. That's a tangent for another day (and another thread methinks)
