You can hear the commentators getting worked up about it and it adds a little fun and excitement to the game especially when he crashes a pack and hands it off like he did to Rayner in the goal square . It can also get up the opposition's nose and if you want the opposition focused on anyone it would be Rhys , not so much our better players. It doesn't seem to detract from his performance.Pretty sure Fagan started the “barometer” talk in an interview, when asked about Mathieson.
There aren't enough personalities in the game , he's not carried away with it , uses it to fire himself up. Which he needs to to play well.
