I think you are, you're saying that Draymond receives as much help on defense as Kawhi does. That isn't true by any reasonable scale..
First of all, just because they hold opponents to a lower shooting percentage at the rim, doesn't mean they're helping Draymond. Most of those shots they defend at the rim are either guards/wing driving into the paint or from guarding their own man - not from helping Draymond on his man (Draymond has less help than every other single player in the league when defending shots). And just because they hold opponents to a lower shooting percentage at the rim doesn't mean they're more important to their team's defense, than Duncan is. Ezeli spent most of his time defending shots at the rim against second units, so you can't really compare his DFG% to Duncan's as if they're defending the same talent of players.
Draymond defended 1,318 shots this season (which granted is only ONE part of defensive play), more than any other player by a considerable margin - Kawhi only defended 676 shots this season - before we even get into all the different shots Draymond defends and all the HELP defense he provides when anchoring the paint/defending the PNR, it's quite clear that Kawhi receives more help on defense than he does.
Duncan has a better DRTG and DRPM than Bogut and Ezeli do, meaning he has a larger influence (in a general sense) on his team's defensive impact than they do.
