Hi,
You are absolutely right that was amazing.... simply incredible !.... however 3 crucial things helped Kansas:  Luck (3 times in a row they shot from far away, under pressure, and made it !).  Bad mistake at entering the ball, some 1'30" to the end, that cause a turnover and 3 point.  That was THE crucial point !.  An exprienced team wouldn't make such a terrible basic mistake.  The terrible misses of 3 (or 4) free shots in a row (until that point he made it 4 out of 4 and his seasonal average is something like 80% from the penalty line).   Great, enjoyabe game, and great basketball !.  
Best regards,
