Here's the shot chart from ESPN on the second half that describes this. It doesn't mean there weren't tick tack fouls called on ISU, or that the officiating was consistent and called both ways. But it definitely shows a massive difference, that TTU was overwhelmingly going to the rim, and ISU was not. That's going to drive a big FT discrepancy. This and the first half shot chart also dispels the idea mentioned that ISU was getting fouled a lot but not getting calls attacking the basket. I recall Jones not getting a call and clearly getting fouled, but it was not too prevalent. Otherwise you would see a lot of missed shots at the rim by ISU. That really wasn't the case. ISU missed some short ones on putbacks and dishes to Rob and TE.
TTU was absolutely determined to get to the rim. They missed some shots at the rim and had some TOs, but they knew they would lose shooting jump shots, and accepted those misses and TOs, and it worked. ISU settled for a really high percentage of jump shots despite not missing many shots on drives.
