I think it's about what kind of signings do we want?
Do we want to look for bums on seats players? If so, Savea in a heartbeat.
Do we to build for medium / long term success? If so, Savea may be a luxury that we can't afford
Do we want to build a large squad with salary cap space? If so, Savea is out of the question
I don't know what our strategy is at the moment with Lima, Fekitoa, JTA, Shields etc.
It's probably just sign anyone who is available and likely to improve the squad
