Here in Los Angeles we have two polar opposites as owners of our basketball teams. Jerry Buss is a ladies man, Donald Sterling has been "happily" married for 53 years! Buss will spend money when needed, Sterling saves his money when needed. Where Buss earned an an M.S. and Ph D in physical chemistry at 24, Sterling opted for Law School.
I'd trade either of them for Mark Cuban.
Cuban dances on TV, spends wisely and speaks his mind. He definitely speaks his mind. His recent assertion of a strong dislike of the basketball team in San Antonio created a rivalry that didn't really exist outside of Texas. Not to say that Spurs vs. Mavericks wasn't a series that would catch the attention of a true basketball fan, it would; but, few outside of Texas would Tivo it.
Cuban saying "I hate the Spurs" changed all that. This is now a full-fledged rivalry with Cuban playing the part of villain.
Which got me to thinking, what other rivalries exist that excite basketball fans? The list was pretty easy compile and presented here in order of last intense to capture-the-nation-intense.
