In this particular context, being there doesn't mean you're seeing anything different than me. In the second half of the season, BD did defer to Monta and Jack. Probably more to Monta though because he was on fire after the All-star Break.
BUT ...
What happened when BD had to get a breather and Stephen Jackson had to run things? Traveling violations, drives into 8 dudes and getting the ball stolen, or Jacking up an 18 footer after 62 jab steps or a pick and pop with Harrington and a bad pass to a fan in the good seats.
What happened when BD had to get a breather and Monta had to run things? If the first thing that they want to run isn't there, no one knew what to do...
Not saying this was all the time, but you came to expect that shit when BD wasn't in the game. Why do you think he played so many minutes and Don Nelson was always talking about how he needs to find ways to get him a breather?
You could also tell that BD was wearing down a bit and wasn't trying to push it to the brink because he wanted to complete a full season without an injury. Gotta factor that in as well
