MRobbo, what makes you say that the doggies are looking to switch?
The is a strain in the relationship between Werribee and the Bulldogs.
Now that Williamstown are not with Collingwood, Willy are very keen in going with the Bulldogs.
Hence Werribee would be looking for an alignment and Kangaroos are the best option.
Talks with Frankston never really got started and the Dolphins will remain stand alone next year.
