It's great that he can run at the edges, but he can only do that effectively if there is go forward provided in the centre of the field by the other forwards. If this is not occurring, Taylor is not a player who can help get that drive going.
For this reason, he would not be a priority signing for any side's pack unless they already had the go forward. Souths already had a good pack, as did the Broncos, and Titans are pretty good in the forwards so these sides are the ones that have been after him. A side looking to develop it's forward pack for go forward should and would not be after Dave Taylor.
