Heise seemed like a good get at the time to be honest. I don’t know what’s going on there. Guessing he’s just not a P5 player. Chat looked good early in the season, but has fell off a cliff. Still time for them to show something if they want or can
They looked good when they had an athletic advantage over the opponent. Much like ISU's offense.
It's been mentioned previously...ISU runs a very simple offensive scheme that IMO appears to rely heavily on athletic advantage over the opponent. That works well for a light pre-conference schedule. It can also work well for the early conference games when the team is still fresh with plenty of energy to expend. It also worked out well for the early conference schedule this year because ISU played some struggling teams.
But now, in the conference grind when running up against better athletes, the simple offense doesn't generate many easy looks, and the improved athleticism of the opponent makes it much harder to finish those difficult shots that were going in earlier.
Nobody is really shooting well for ISU now. Poor shooting kind of boils down to a few things...1) shooters are exhausted (mentally and/or physically), 2) the shots they are getting/taking are too difficult, or 3) the shooters are outmatched athletically by their opponent.
