In January 2023, the NCAA allowed teams to increase the number of assistants to 5 from 3, with the two extra assistants not allowed to recruit off campus. This really didn't change much because non-coaching staff members were already allowed to do some skill instruction.
As of today, ISU promoted Emily Hatfield and Rob Jenkins to those assistant positions.
(Note: I don't think the tweet intended to imply they would be doing any off-campus recruiting, although I suppose they might be able to participate in recruiting road-trips as long as they don't do any actual recruiting on them.)
