The article mentioned that closing main roads temporarily could have a similar effect - could teams thus experiment with benching star players , or altering plays to "mix it up" more, without actually losing the player? This would seem to be the best of both worlds, by using the star optimally.

In general, this seems like a lesson to not focus so much on the "strongest point", but try to squeeze out more returns from weaker points before diminishing returns set in so heavily. E.g. - don't make your strongest developer in a small team do all of the hard work, even if his code is much better than others'. His ninth hour of work is less productive than another developer's second.
