Does Dray or Bogut guard Blake?

I'm having an argument with my friend about this.

I say that Bogut guards Blake at least 50% of the time and he says that it is more like 85% Dray and 15% Bogut.

Is there any way to check this (other than rewatching games)?

Dray obviously, so Bogut can come and help.

I'd prefer thoughts from people that actually watch the games.
