There has been a change to the starting lineup (Jase Richardson starting with Tre Holloman now coming off the bench) but Tom Izzo has stuck to his 10-man rotation throughout the season. And with great success so far.
It seems like the best bet is for that to continue as long as this run lasts for the Spartans. Izzo has previously stated he expects to stick with the ten-man rotation but also that the minutes distribution may change with performance.
So, in trying to predict what might happen in the B1G and NCAA tournaments, it might be helpful to look at how things are trending as the regular season wraps up (hopefully with an outright Big Ten Title for MSU).
