Sounds like Bird is being signed to basically plug holes. He may force his way into a permant spot, but will always be the guy that covers injuries throughout the team. It's a role that Adam Doueihi should have been able to fill, but we know what he would do if thrown into the backrow. So Bird for 2 years is good IMO. My Dragons mates reckon he is near their best player when he plays.
Our side will have a very different look next year, but more importantly it will be full of personalities that we have not had for a long time.
