Built - do you buy into the theory that playing heavy minutes has a cumulative effect?
In other words, a player who logs heavy minutes every game accumulates more wear and tear, and is more worn down by the end of the season. Whereas, a player who logs fewer minutes avoids some of that wear and tear and is a little fresher at the end of the season, making them better able to handle heavy minutes in a conference tournament situation.
I tend to subscribe to the theory that, if you can get guys some rest, especially early in the season, do it. that extra 4 or 5 minutes a game may not seem like much, but over the course of the long season, it has an impact. at least IMHO.
Not to mention the fact that some guys, for reasons of genetics, body type or whatever, just seem to be able to handle heavy minutes more easily than others. very important for a coach to know what his players can handle - some guys are just different than others.
