As I've said 100 times, it's not ONLY the arena that results in win. Of course, the Coach is huge. To win in this world over the long haul, you have to be firing on all cylinders. A++ coach, facility, AD. Any weakness makes it very hard, though not impossible, to win. Of course, landing miracles like Tim Duncan and Alondes Williams, whom no one else was recruiting, helps a great deal. And those flash in the pans will always happen on occassion.
22 likes to say "but Duke has better players." Yes, of course they do, and as K will tell you, the proper venue was one of the critical cogs in getting them there.
Those who think Duke's success is ALL because of Coach K, forget that in the 20 years before K, Duke accomplished more than we have in over 100 years of basketball.
