Perhaps Jordan Spence would actually be outmatched defensively in unsheltered minutes (seems DJ Smith assumed so because he's so lil), but I do wonder how Sanderson would look alongside a more offensively capable defender like Spence. At least in offensive deployment.
I don't see Sanderson as a player like Karlsson or Chabot who needs a cautious safe player to cover for him - his defense has always kicked ass. Zub is great defensively and adequate in transition, but maybe we could try giving Sanderson a partner with offensive chops like a discount Hughes/Hronek.
