What am I missing in Wojnarowski vs. David Kahn?

Are Kahn and Woj even of the same vintage that they would have run in the same circles when Kahn still was a sportswriter?

I suppose that if Kahn had been, in Woj's opinion, a quality sportswriter, it would be harder to destroy him as a rotten GM. Or it would make Adelman's dislike of him way back when a little unfair and unprofessional on the coach's part. So the broad brush must be hauled out to make the column work in its entirety.

I'm thinking some agent(s) on whom Woj leans so heavily in his work don't like Kahn and maybe didn't think much of him as a reporter and writer back then.
