Quote: saint at wire "Why don't we just sign another good half for next year if no Walsh?'"
Historically, having home grown talent in the halves gives you stability and a good chance of longevity in success. If you look at early Saints, Bradford, Leeds and partially Warrington they have managed more consistency in the silverware department.
Changing you half backs every season with short term overseas players is not ideal, I think Hull KR, Wakefield, Catalans etc for example is not a recipe for success.
