They can't shoot if they don't have the ball, or don't have the ball in a position to be able to shoot. As far as I could tell, Hare and Jackson shot every time they had the chance to. Baylor was only backing off of Williams and Beatty--Iowa State's only two guards who are shooting under 35% from three.
And that's where
@BillBrasky4Cy's point about more movement or shot creation for others has a lot of merit. I disagreed in that discussion after KU, because KU was willing to defend Audi with one player, and there are very few times where Audi Crooks one-on-one in the post isn't about as good of offense as you can get. But with how Baylor was defending, Iowa State needed to do something much different, and it was definitely coaching failure to not have anything ready.
Even just trying some different things like having Brown, Hare, or Jackson initiate the offense, or play Wilson in the minutes that Williams was sitting, would have been a starting place to not just let Baylor do the same thing over and over.
It will be interesting to see how teams defend Crooks and Iowa State moving forward. Baylor's strategy seems like an effective one, but Baylor also has more length than a lot of teams--to be able to simultaneously double Crooks with two players at or above 6'0", while keeping another on Brown.
