Yeah, I think papalii as an impact middle off the bench, or starting, would be really good. He runs out of puff too quickly for us when on an edge and lacks lateral movement for defensive work, but in the middle he is just able to run and hit and then get a break when he gets puffed and he does that well. We have no one with his physicality on our team and he is a loss.
However, it was obvious even from before he came here that he didn't want to be here. I'd guess he's been pushing hard for a release ever since.
