5.03 doesn't count, I'm sure, because Dean didn't let Sam join up again immediately and there were too many Dean and Cas shenanigans. 5.18 wouldn't count because Dean's beating was more dramatic and Sam wasn't the one to beat him up.
Gamble didn't write all the Sam centric eps but she was the showrunner who would have approved them, so she gets credit for them. And now that she's off the show, she's a much more appealing candidate as a Sam-favoring writer. And Edlund? PLEASE. That man keeps shoving his Dean/Cas fuckfest down our throats. That he wrote most of the Sam centric eps just means how low we've sunk and how bad the Sam writing is these days.
In case it isn't obvious, I don't believe any of this myself. I can see someone else believing it though, especially if they're looking for any reason to be unhappy about Sam's upcoming role.
