Fouss showed at the end of last year that he is a liability against the PnR and basically unplayable against a 5 out offense.
Young is obviously recruiting players who can switch and defend multiple positions. I am not saying Fouss will not play but unless he improves on perimeter defense he very well could be a situational player vs traditional post players.
If you want to win in CBB, defense travels and defense wins. Look at Iowa state and Houston in the big12 and UConn in the ncaa tourney.
