Well presumably he wouldn't be worth anything at the trade tableNot sure I understand the part about Newman - they want him to wait until after the trade period to discuss his future. So presumably he's not going anywhere, otherwise they'd give him the opportunity to find a new club? Do they just mean contract negotiations?
so
If we pick up 2 or 3 big fish it could push us to the limit salary cap wise and we may not have room for him
or
We are unable to determine what we can offer him before knowing who's coming in thus he has to wait until the end of the trade period before he finds out our offer
