If he could return to his form of around 2014 he wouldnt be a bad shout.
Runs good lines and quite good defensively.
He may not have the international CV like Tupou has but also wont carry the international sized contract either. But that could mean more money could be used toward another prop or hooker.
Like Vastman has said several times we dont have the pot of money that others have.
Personally, if we could get an extra prop, I would use Simon or Arona in the back row so it would reduce the need to spend big money on a second rower.
