The primary reason of this losing streak is injuries. It really can't be denied.
Saying that, these losses also show 2 things:
- First, Spurs third stringers have been just bad this season. Spurs have a core of 9 good/great players (Parker, Mills, Belinelli, Green, Ginobili, Leonard, Diaw Splitter and Duncan) and behind them it has been quite a disaster. None of the other players has been able to step up.
- Second, Spurs didn't do enough this offseason. There were opportunities through trades and/or cap space to make something significant this summer but they wasted them.
