Spurs best NBA team now?

I'm a die hard spurs fan, best team now-a-days,if spurs win tonight they take the ring.They are streaking at right time just like always. Celtics are not unbeatable.Spurs lost bad first time, but both teams missing key players.(T.P. & K.G.)Second time spurs went up 20+ points, but lack of second half calls, spurs lost by only 2 points.(celtics more than 2X free throws)
