The Golden State Warriors have not even raised their championship banner, yet they are already defending their title from vocal challengers ready to debunk their success ahead of the 2015-16 NBA campaign that opens on Tuesday. Led by league Most Valuable Player Stephen Curry and first-year coach Steve Kerr, the Warriors capped a 67-win season by winning their first NBA title in 40 years last June yet somehow failed to make believers out of their competition. During an offseason of opining, Los Angeles Clippers coach Doc Rivers implied that Golden State were lucky to avoid injury and his team during their title run while Houston shooting guard James Harden said he should have won the MVP award over Curry.
