The lack of attacking intention from our regular left back actually frees up the right back to get forward whenever he can - Coleman demonstrated this against City. You have to assume Youngy knows his legs won't stand up to bombing up and down the wing for 90 minutes so his forays forward are limited but on boxing day Seamus showed us it's not a management instruction that fb's can't attack or overlap.
The only question left is why has Nathan Patterson not done enough to cement a place in any team he's ever been in? We can throw faux outrage at the vicious tap to the back of the head he received on a team jolly which has recieved infinitely more airtime on this forum than anywhere else it was mentioned, but Dyche is a man who now has a hell of a lot to prove to the new owners - is he a manager who can take us forwards or has he served his purpose in keeping us up? The fact he doesn't trust an attacking RB in a team struggling to create chances, even though playing him has the potential to enhance his reputation as a manager, suggests that Patterson truly just isn't good enough to be a regular in the premier league.
