It is a very interesting theory, and one I think is completely valid. I would add some others (linked ):
Brian and Evan are more or less the last of a generation, a generation which is the last to have known the old judging system and a generation that is inspired by Yagudin, Goebel, Stojko, Abt and so on. When one looks at the current skating scene, one can see that there are a lot of talented young skaters, but skaters that one generaly has trouble imagining as tomorrow's heavy-weights. A lot of these kids have loads of talent, but because they spent most of their competitive career skating under the current system, they have good footwork, good spins, intricate choreographies, but they don't take risks, they don't do programs with lots of "oomph". The old generation may not have a some of the qualities that these new skaters have, but they know how to work the crowd, they take risks, they make competions thrilling.
I think also judges are starting to realise that the kind of skating the current system encourages is partly responsible for dropping popularity.
These new skaters all skate alike, there are no strong personnalities, original styles, out there, which is what makes the mens' event what it is.
Patrick, I think is an amazing skater, but because he is the leader of this new generation, it's via his grades that judges are sending out the signal.
