Perceptions are a funny thing WP.
I think you'll find that the stats tell us a different story.
Maybe that there really isn't much difference between Grigg and Petterd last season.
Argh Yes, Stats. Those things that can tell any story you want them to tell. Hence, why I don't read much into them. I put much credence on what I witness first hand on the field.
And based on that there is a missive difference between Petterd & Grigg
And you are certainly right about perceptions
