I think it's more walking the ball up the court after makes or misses, running the offense, and then putting on at least token full court pressure - that will slow the game down enough that hopefully Illinois doesn't get in their flow with runouts, etc. Shannon likes to attack, even 1 on 3, before the defense is set and mitigating that, making him get shots late in the shot clock, will be huge
The game will probably be in the 70s, but if its in the 60s, we have a great chance of winning. If its in the 80s we have very little chance of winning.
I keep saying it ad nauseam but the achiles heal for ISU looks to be patience when the game speeds up a bit; if ISU does get a run out it will come down to them securing the ball and kicking the ball back out if the easy bucket simply isn't there.
They don't need to bleed the clock, but just make sure it's a secure look.
