Watched him do plenty on the field & be a big contributor to the achievements he's earned in his career. You know we weren't the only club chasing him & offering him those sorts of dollars so it's not just the Wests Tigers who valued him pretty highly & this was all before he filled in at halfback for Penrith last year & did a pretty good job at it too. By that metric is Nathan Cleary a failure because he's directly contributed to Origin losses too (yet to win a decider as the halfback actually)
The only other club seriously chasing him if I recall correctly was the Dogs, and they didn't come close to the number we did (their number was closer to Penrith and that's with Gus and Ciraldo who were intimately familiar with him from their time at Penrith).
And Cleary is a failure at origin level. No arguing that. But at least he's proven he's an all time great halfback and no.1 option at club level. Luai's proven he's a nice to have as your 3rd or 4th best spine player.
Also I put little stock in what Luai did filling in at 7 last year because Kenny and Yeo still organised the team in the middle and we're seeing Brad Schneider do just as good a job this year.
