I don't think Godfather is lying at all.
I just think it's very clear why The Rock was turned heel and put in The Nation, and it had a lot more to do with putting him on the path to becoming a star than getting veteran guidance.
Again, if he really needed guidance from veterans, he wouldn't need to be put in a storyline wrestling stable to get it. Young wrestlers get guidance from veterans all the time without being placed in their storylines.
So my guess is that Godfather is seeing things from a slightly biased and unrealistic viewpoint there.
But hey, he seems like a good dude and I like the interview.
