I am not a Knights fan so no emotional attachment here, but the Knights have obviously received feedback from their fanbase early in the season letting them know that they love the heritage jersey and hate the blue jersey.
Maybe they based their decision on jersey sales, or maybe they just plain realised they'd made a mistake and the heritage jersey or a striped jersey is the way forward.
Either way, I'm glad the club has acknowledged that it made a mistake with it's choice of home jersey and they're keen to drop it. I don't have any problem if the club chooses to wear a jersey the fans love rather than one that is universally disliked.
