Good read.
They've been ok signings (marginally better than some of the local options, but not by much).
Not sure they've done enough on the field (from the little I've seen this season) to justify their inclusion. If they're not going to be challenging for the playoffs, you'd be better off providing a local pathway.
While it's mitigated slightly by some of the off field roles, personally I'm a bit uncomfortable with some long term staff being moved on in order to accomodate them.
