Yeah, I have always thought it was crazy and interesting how the makeup of our conference has historically seemed unique in this regard. We have a surprisingly great / large group of "second tier" programs with great histories, but nobody comes close to a Kentucky that can carry a conference with a lot of titles.
Rewind to just after the 2005 NCAA Tournament, one year after we made our fifth Final Four, five years before UConn got National Championship #3 out of what would become six and well before the more extreme conference realignment that was to come. The National Championships and Final Fours makeup of the conferences is interestingly different.

TL;DR
The Big Ten has been a historically very deep league, and other than a period of dominance by Indiana that is ancient history at this point, we have not had a Blue Blood to boost our National Championship totals. Even still, we have had a way higher percentage of our league make it to the Final Four several different times, unfortunately coming up short. However, when you isolate Blue Bloods that are totally carrying their conferences (e.g., Kentucky in the SEC or UNC/Duke in the ACC) and compare it to an Indiana-less Big Ten, the rest of our conference is much better than the rest of everybody else's.
