Idris would be worth a risk depending firstly where his head is at, and secondly how much cap he chews up if he's a fail.
200k of cap space is doable wasted, FFS we had 2 million sitting on the sidelines this year in Watmough and Foran alone.
At his age, if committed, he still has a fairly long career ahead of him, redemption isn't beyond him with the right attitude, and it's worth remembering that even as a lazy prick he still had the talent to play origin and for Aus.
Still, I don't think we need another second rower, it aint where we are lacking quality.
