Should flacks write about old-media hacks?

David Guarino has been writing a fair amount of late about our boy Brian McGrory - praising him as the best columnist in the city (Ed. note: What was that sound Bill the Cat used to make?) and speculating on whether Brian McGrory is now The Man among Globe metro columnists (both of them).

Now, Guarino used to write for the Herald, so he knows Boston media. But he also used to be the p.r. person for Tom Reilly, whom McGrory composed hagiographies of while others were ripping into him for, oh, pretty much everything. And now Guarino reps for state House Speaker Sal DiMasi. All of which leads to Adam Reilly's question: Should the p.r. person for one of the most powerful politicians in the state be commenting on media happenings?
