Kruger uses big men. Probably doesn't use it enough at OU but used them well at Illinois and UNLV. I do agree though that Lattin and McNeace are under utilized.
Part of me wonders if OU would be much better at this point in the season if he didn't have Young dominate the ball so much. If he developed the players and roles of the other OU players more earlier in the year. I think OU is going to struggle majorly again next year and it's because Kruger didn't develop the rest of the OU players this year to be better and more comfortable making plays.
