I suspect Fred's NBA experience is helpful in managing a 5 1/2 man roster. My random sample of NBA stats reveals that most teams have 6 primary players, who all average in the high 20 to low 30 minute range per game. It's not that big a deal.
What matters is what happens on the off days. NBA practices are surprisingly casual. Lots of teaching- putting things in, walking through tenancies, that kind of thing- but not much full-out scrimmage once the season is underway. There are just too frequent, so rest becomes imperative.
I imagine Fizer wouldn't recognize an ISU practice today- lots of teaching, not much running, trying to preserve legs when the spacing between games is short. The "practices harder than the games" mentality will have wait.
We'll see if Fred's recipe can maintain the same effort once we get into the Big 12 season.
