I always viewed Bob as more of a "statistician" than "historian." Doesn't matter, he's been around a long time and has seen a lot. Like anyone in this sport and industry, he has his fans and his detractors. When he used to do the show, if he wasn't in that "stat" mode, I though he brought a good perspective to the discussion. I never thought he was a great handicapper, but that's OK. JMO.
But, being around a long time and having seen a lot, either you learn a lot or you think you've learned a lot, LOL. You decide which category Bob falls into, LOL.
