I've seen the rumour and think its a non starter.
first off i don't think that's how Price does business. i.e shipping a player out who has put a shift in all season (despite what people think of his ability) who most likely doesn't want to move, and doing it a week or two before pre-season starts. This smacks of Tony smiths style desperation tactics towards the end of his reign, when he didn't care how moves may have affected team moral.
I believe Price thinks Brown deserves to have a season alongside Austin.
I also believe that Brown would retire rather than uprooting his family and going to London as per the rumour.
I think we have a little bit of money left for a surprise signing like Bodene Thompson but that's it.
