PSU obviously is a great program historically with incredible resources if the right guy is in charge, but ... I have always liked that Illini Basketball isn't solely reliant on one "legend" for our historical success. Sure, Lou is a legend ... but John Groce is the only Illini coach in the last 50+ years to not win a Big Ten title, with 4 of the 6 in that time winning multiple Big Ten championships, 4 of the 6 earning a #1 seed, 4 of the 6 making at least one Elite Eight appearance and 2 of the 6 reaching a Final Four.
I feel like programs like Nebraska football, PSU football, Indiana basketball, Syracuse basketball, etc. who are SO reliant on one legendary coach who elevated them into the stratosphere during his tenure often then slide back down to Earth and have an identity crisis, lol. Some programs correctly leverage the legend to maintain elite status (e.g. Duke basketball), but man ... I think PSU is about to have their Nebraska football moment.
