I looked at Iowa's losses this year to see how many 3's we've made per game, and how many our opponents have made, and calculated the point differential based on made 3's.
Villanova: 11 makes. Gave up 14. So that's -9 behind the arc in that game (3 more makes times 3 points)
Wisconsin: 4 makes. Gave up 10. -18 from behind the arc.
@ISU: 4 makes. Gave up 6. -6 behind the arc.
@Michigan: 2 makes. Gave up 8. -18 behind the arc.
MSU: 3 makes. Gave up 10. -21 behind the arc.
Sure, you have to assume that Iowa is making some 2's or getting to the FT line on some of the possessions rather than making 3's so you can't totally look at that stat in a vacuum, but it's hard to ignore the fact that in our losses, the 3 ball has been a decidedly better weapon for our opponents than it's been for us. Particularly in league games.
And yes, I do agree that the FT shooting in key spots in the game has to improve. That beat us in the ISU, Nova, and MSU games for sure. Still, better 3 point shooting would also have helped in some of our defeats.
I'm not really in love with the thought of jacking up 3's every time down the floor, but basic math will tell you that getting 2 but giving away 3 is not a winning formula. Iowa needs to either start making more threes, or allowing less. Or both.
