His playoff numbers are even less impressive when you factor in who the few big offensive series(statistically) came against.
1 was the 1990 Nuggets who defined the run and gun style.
27.7 ppg, 59.3 FG%, 63 TS% (pace in the series was 108.8)
The next series vs Portland he was down to 22.9 ppg on 50.4 FG%/55.8 TS%
Not bad, but not great and among the better series from his prime.
His playoff numbers also benefited from the run and gun early 90's West when he faced the Run TMC Warriors. When you see his numbers, you'll think he dominated.
25.8 ppg, 68.6 FG%, 76 TS%
But watch the series and not only will you see that he wasn't taking over those games, but you'll hear the commentators mention that his numbers seemed quiet. And then keep in mind that the Warriors were the 5th worst defensive team in the entire league and that Robinson's 55 win Spurs lost to the 44 win Warriors.
In fact, it was very normal for stars to put up huge numbers against the Warriors of this era. And this is one of the cases where the numbers look a lot better than the impact, as evidenced by him losing in 4 games to a team that won 11 fewer games.
The 3rd big playoff series offensively came against the '96 Suns when he averaged 30 ppg on 55.6 FG%/62 TS%, but similar to Golden State in '91, Phoenix was the 7th worst defensive team in the entire league(in a league with several expansion teams), and the worst in the entire playoffs. You'll see the drop vs Utah in that same playoffs.
And then there are these other series from Robinson's '90-'96 prime.
1993 1st round vs Portland- 19.3 ppg, 42.6 FG%, 48.7 TS%
1994 1st round vs Utah- 20 ppg, 41.1 FG%, 47.1 TS%
1995 1st round vs Denver- 19 ppg, 42.9 FG%, 49.3 TS%
1996 semifinals vs Utah- 19.3 ppg, 47.5 FG%, 52.6 TS%
Shows you that he was never as good of a scorer as his regular season numbers suggest. Choker.
