Injuries and fatigue

I do not generally like rotations quite as long as Beard had them last season. It makes sense to me that throwing players in and out of a game tends to disturb the continuity of the team on the floor. However, if fatigue makes players more injury prone, it might have definite benefits there. We did stay injury-free last season except for Daniel Green. So there are benefits on both sides. And I am no physicial therapist. Nor a coach.
