We're reinventing history with 2006. We were pessimistic at the start of the year due to suspensions, then optimistic when we went undefeated with Austrie at the point, including the Maui Tournament, then got slapped in the face by Marquette who just ran circles around us and almost scored 100. After that, we showed some flashes, but we couldn't match up with Nova the first time, and limped thru Feb and March with mostly close wins over bad teams (and one A game in the Nova rematch at home). The regular season record did not reflect the product we were putting out there.
We were simply not way better than our opponents every time we took the court. In March, we were down big to Syracuse and got lucky to comeback before McNamara beat us. We were down big to Albany (frankly until they got a little over-excited that they might be able to actually pull this off and started missing open shots), we couldn't defend Sparks from Kentucky and gave up 80+ points to an 8 seed, we got gift-wrapped the UW game by the officials when we were on the verge of being run out of the gym, and we couldn't guard anyone on George Mason.
Who was this team so much better than?
I'll say this - the 1999 team did sometimes have a problem with letting inferior teams hang around. But you will never see a college team any better at putting the clamps on in winning time. Even the one game they lost at full strength, the only points Miami scored down the stretch (last 5 minutes) were when Tim James caught a desperate airball with a minute to go and got fouled on an iffy call (but Jake probably bumped him).
The 2006 team didn't have a clamp in them - they couldn't stop anyone when the chips were down. They kept thinking they could just make more clutch shots, and through February it worked for some close wins. But you play with fire often enough, sometimes the other team makes more clutch shots (see: Orange, Syracuse; Mason, George).
I believed that 1999 team would come through. Two big-time scorers with the clutch gene, and a defense that would just lock you down. The 2006 had the first (MW, Rashad) element, but might have been the worst team we ever had at the second (at least among our contenders). The evidence was there in spades before we lost.
