The Spurs with just Robinson finished number 1 defensively more times than the Magic, stop it.
Why don't you make a topic "Dwight Howard vs David Robinson" and see how you fare
Cummings, Hot Rod Strickland, and Sean Elliot were all very credible defenders.
Turklglu, Lewis, Redikk, and Nelson are not credible NBA defenders in any era.
You are comparing oranges to apples.
Look at the Squrs in the playoffs

GSW 3-1. They were attacking the paint and shooting SAS out of the gym. Where was D-Rob? Game 2- 5 TOV, Game 3- He didn't close the lane and Sarunas was raping them.
Game 4-6 TOV and Tim Hardaway was attacking the paint like crazy that game.
1991-

No comment they got swept in the 1st round again

1992- Finally got to the 2nd round and beat a credible Blazers team. Took Phx to 6. Breakout year.
1993-

1st round exit
1994- They had an excellent team that year. I remember watching those Squrs games like

Got to the WCF. Dream worked D-Rob like a bytch.
1995- 2nd round losers.
1997- Duncan's rookie year. R-Rob had a better year than TD stat wise. 2nd round exit.
1998- TD is their best player and they win it all.
This is your boy's track record. He's mainly had the same cast for most of his years replace Johnson with Strickland and Duncan with Cummings.
