Crazy that they'd put Boise St ahead of your Hoosiers. Boise St has half as many wins, only having beaten Portland St and Georgia Southern. IU has 4 wins including one over a Power 4 team. ESPN's Power Index has IU at 15 and BSU at 27

I think the Hoosiers will be well inside the Top 25 seven days from now
