Kalkbrenner is a lot better than Goldin. Kalkbrenner is pretty close to a perfect college center for 2023.
That said, SDSU is a really interesting matchup for Creighton. That SDSU team is physical on both ends, and could wear Creighton down given Creighton's weak bench.
This is kind of crazy to say, but Alabama might have been the better matchup for Creighton. Alabama was a bit overrated all year, racking up wins against a bunch of mediocre SEC teams, and the pressure on them was off the charts given all the off court stuff. Miller is playing on a big stage for the first time, and it got to him. Also, Quinnerly is a full blown dipspit of a player too, which could keep any opponent in the game. I don't get how his teammates don't want to kill him with the terrible, selfish decisions he makes.
