For me the big issue with Marcus is consistency. He's just not reliable enough game to game or even over 80 minutes. I feel he's had enough time to make the shirt his own and he hasn't taken it. Maybe it's being behind a beaten pack, but based on this performance Fin has to start next week.F Smith showed he's can be a test level FH but that doesn't mean Marcus isn't. F Smith might be more suited to England or might I say England might suit F Smith more due to the way we play.
I also hate to say this but Marcus didn't play that well at FB but I do think he could be outstanding there with time (not that I want that).
