The depth chart.
I mean, my understanding is that the coach plays your backups during garbage time right?
So my rotation is set up so I have a starter or two out there, or I have a guy that could easily start, come off my bench instead. OR maybe I do both.
I agree with this and use it myself often. Sometimes I actually pull away farther because my shooters get minutes, and my defensive guys go to the bench.
However,
Looking ahead and hearing from players in higher divisions, I am betting it becomes exponentially more difficult to have a strong bench in relation to your starters, and still be competitive at that higher (est) level. Not sure, havent been there, but I scout alot :)
