I really dont see what the big downer is regards Lauaki.
For a start even if we do sign him we'll still have Fielden, Lima, Prescott and Mossop plus the Hock and Crosby. If he's a cheapish option to add depth to our front row i think it could be quite an astute signing as he has bags of potential.
If we got him say on a one year deal with a futher 1 or 2 in our favour looking at him to improve his all around game. Mainly his structure within a team and ill discipline it could work out brilliantly.
One things for sure this "potential" kind of signing wont be like Karl Pryce. Lauaki will never be questioned for his passion and commitment.
