I think people carry on a bit too much with this captain/coach idea, he's a very experienced player in a very important position, whilst Kev isn't a seasoned veteran in the coaching ranks I can assure you he's no mug himself, they'd bounce ideas but I highly doubt Adam Reynolds is coaching the side or insisting the ball go a certain direction.
My gut feel is that many want to believe Reynolds is coaching because that would then take the gloss away from Kevvie when we do have a good win against a top side, suddenly Reynolds gets the credit and not Kev. Which is ideal, for those who think Kevvie can't coach.
