I wouldn't call him over-rated, it's just the wankfest that's annoying.
You won't hear squat from commentators when he f**ks up. But he can do the most minute thing & he'll get all the credit every week. Example: Marshall throws a simple pass to Florence, Florence runs it, draws two players, & set up Fai Fai Loa....... yet "Brilliant from Benji Marshall!". Same thing happened with the Hayne wank-fest of 09/10.
That said, Marshall has numpties like Lui/Moltzen/Miller to work with, so he's carrying the team.
Foran needs to stop being in awe of Marshall at International level & take some control.
