Bob was well connected, knew the league better than anyone, and was a true professional.
But I think one of the things that really set him apart was the fact that he was almost always %100 sure about something before reporting it. He never had 31 stray thoughts, and rarely confirmed something as done when it wasn't.
Seeing a bunch of junk thrown at the wall is really annoying as a fan, like with the current Chychrun stuff for example. It makes it more fun if you pay less attention, because then you don't have to sift through the junk. Making it worse for the hardcore fans is a bad idea.
Bob made sure that people paying more attention got more out of following the sport. It's a subtle difference. But it is a big deal over the long run.
