Spurs has made playoff 20+ seasons in a row, there is really no other franchise that is as good as them at longevity, they are also 5 time winners in that 20 year period as well. So, I do like them and I trust their capabilities as well but right now it is just too late. If it was regular season and there was some more games left maybe they could have but unfortunately there isn't that much game left and all of them are against high level teams so it is not going to be possible for them I believe.
It is okay though, they are still young, from Murray to White to Walker they have great youngsters, Jakob has been playing very well too, so they actually have a great young core that could get better with time, so they can miss the playoffs as long as they keep on improving with the team they have.
