It's a 6 game tourney. And, no, a cakewalk means more than no tough games. You can have a tough game against Albany. That doesn't mean that getting Albany as an opponent ends the cakewalk. Or you could annihilate a #1 seed in the championship game, but the fact you killed a #1 team doesn't make it a cakewalk. A cakewalk is simply not having to face the stiffest competition. UConn faced Duk, true, but no other resistance. Compare that to 2011 when one could easily argue that Arizona, Butler and Kentucky were the best teams in the tourney other than UConn.
In 2004, Stanford, Syracuse and Maryland were eliminated in UConn's bracket, so they took on 8 seed Alabama in the F8.
Meanwhile, Kansas and Kentucky were taken out by Georgia Tech, a 3 seed. Good team, but hardly top caliber.
Duke was legit (and were it not for Emeka playing only 2 minutes in the first half, UConn would have beaten them by at least 10).
If UConn had to face one of Stanford, Cuse or Maryland in the F8, and then Kentucky in the final, that would have been as brutal a path as it took in 1999.
