San Antonio was consistently the best team in the league all season long (them posting the best record in the NBA should've told you this). They also won 12-14 of their playoff wins by double figures. You really don't know much about basketball besides what first take used to tell you it seems.
Of course they had the best regular season record that year when their two closest rivals in their Conference were crippled with injuries (OKC: Russell Westbrook played 46 gms.; Clippers: CP3 played 62 gms.) and the Heat strategically taking games off. If you're that easily impressed then that's cool.
And put that "12-14 of their playoff wins by double figures" in proper context. They got four of those against an overachieving Blazers team that pulled off a shock upset in the Round 1 over the Rockets that year and were no match for the Spurs, in addition to another three coming against a Thunder team that were without their best defender Ibaka for the first two games and another one with an Ibaka who wasn't even fully recovered. The remainder came against the Heat. Stop promoting this false idea that the Spurs had some sort of uncontainable offense that year.
