It looks like Altman is letting Garza get his mismatches on the offensive end and figures Oregon will get their mismatches on the perimeter. That will work as long as Oregon continues to hit 3s.
One really good stat for Oregon is Lawson, Omoruyi, and Williams all have 2 fouls or less. Garza could easily foul out all the forwards on Oregon. Let him go early, if he's really deep in the paint. Those fouls are going to be crucial, IMO.
