I'm not sure if this accessible to non-subscribers, so apologies if not:
Is coaching experience associated with effective use of timeouts in basketball?
It's basically a statistical analysis of timeouts in basketball showing that they essentially make no significant difference to the outcome of a game.
They then looked at how the effectiveness of timeouts correlated with the experience of the coach making the calls - and found that more experienced coaches actually have negative timeout factors (ie their teams tended to do worse in the period immediately following a timeout). By contrast, less experienced coaches have slightly positive timeout factors.
They also tested for an association between the effectiveness of timeouts and payroll, and found none.
It's all quite geeky stuff, I suppose, but I found it interesting even as a non-basketball fan.
