Reading between the lines, I suspect that Menzies has a firm offer from another club.
Clearly, he is also ###### off with Bradford not making a commitment to him. If he didn't want to stay in the UK he would have said so. I suspect that he he has no decent offer from Australia. So I think he has been made an offer by another SL club and he is telling Bradford to go stuff themselves.
This rebuff of Menzies by Bradford is surely Mick Potter's decision since he is the confrmed coach for 2011. Potter may not have seen all the good games that Menzies put in during this year. Potter is probably just basing his decision on Menzies' age -- which is really dumb, because Menzies is a renowned fitness fanatic and has not an ounce of fat on his body.
No decent offer from Manly, you mean. Beaver is on record as saying that he would play for no other Ocker club.
I doubt Potter wants to release him - not whilst Hall is at the club - but unfortunately, contracts exist and as Menzies is out of his and Hall isn't, the decision has been made for him. With Bradford being quite strong in the back row (and with Elima slated to join) Menzies cap space and quota space could be better utilised by the Bulls in signing a stand-off or centre - although they will have to go some to find a player that offers as much individually as Beaver.
There is also the possibility that Potter has a replacement in mind and that this person is going to commit for three or four years - something Menzies won't be able to do.
I also don't see why he is 'clearly' ###### off - he might well be, but perfect professional that he is, he has thusfar not shown it.
