C'mon....Timmy was obviously a foundation (and he didn't leave, he's now an Assistant and sometime Head Coach)! But, Timmy was not the whole of the Spurs. The team is always upfront.
(All that said, I miss seeing Timmy, Manu, and Tony doing their thing. Still, LA, DeRozan, DeJounte, Forbes, White, Gay,Walker IV, Poetl, and don't sleep on my Australian with superpowers, Mr. Patty Mills....).
