Let's take a look at the top 20 defensive teams this year (using DEFRTG) and list the good defenders they have at PF and/or C:
- Boston = Horford, R. Williams, & Tatum
- Phoenix = Ayton & Crowder
- Golden State = Looney & Green
- Miami = Adebayo & Tucker
- Memphis = Adams & Jackson
- Cleveland = Allen & Mobley
- Dallas = Porzingis, Finney-Smith, & Kleber
- Toronto = Siakam & Barnes
- Los Angeles Clippers = Zubac, Batum, & George
- Philadelphia = Embiid
- Utah = Gobert
- New York = Robinson
- Minnesota = Vanderbilt & McDaniels
- Milwaukee = Giannis &Lopez
- Oklahoma City = Poku & Favors
- Denver = Gordon
- San Antonio = Poetl
- New Orleans = Valanciunas
- Orlando = Carter Jr & Bamba
- Brooklyn = Durant
The path to becoming even a top 20 defensive team is extremely difficult if both your PF & C are below average defenders.
If the goal is to build a winner, you need to be at least respectable on both the offensive & defensive side of the ball. To be respectable defensively with Sabonis as your C, you really need to put a solid defender who can help protect the rim at PF, and if you want to be respectable offensively (or a great offensive team), ideally that PF is going to be able to shoot the 3 & space the floor.
