UConn made the tournament in 2016 so let's say the last 4 years were sucky. Really only 3 years since they weren't bad last season. I think every program has some downturns.
Most say Indiana is a blue blood. Between 2008-2009 and 2010-2011 they went 6-25, 10-21 and 12-20. You can say the B10 was better than the AAC but those are still 3 way worse years than UConn had. Plus Indiana hasn't won a national championship in 33 years, since 1987. 33 years is a long time. Since that championship they've been to 2 Final Fours, in 1992 and 2002. Hardly a record of a blue blood over a 33 year period.
Since 2003 they've made the NCAA Tournament only 7 times and only gotten through the first weekend three times, in 2012, 2013 and 2016 when they made the Sweet 16 each time.
So why has Indiana held on to their blue blood status? Did they have a longer sustained period of success than UConn and it would take a longer and much worse period to knock them out of that blue blood status?
They don't seem to recruit like a blue blood program. A good B10 program, but not an elite program.
So is Indiana still a blue blood? Why?
