In non-conference, ISU's turnover rate was consistently fantastic, even against the better teams. In conference, it has regressed to just okay/average and as noted by
@rosshm16, it feels like a lot of the turnovers have been unforced.
It seems to me like part of that is increased workload and pressure on the guards, especially since MM has been out. For instance, Jones has played 36, 36, 34, and 40 minutes in the last four games, and has 11 turnovers in those games to match his 11 in the entire season before that.
