Both make good points, but each individual player in question needs to be considered differently, not just a blanket position of "we don't offer contracts to over 30s for longer than one year"
With Adam, I think he deserved to be given what he was asking for as a minimum - 2 more years. If he is such a risk of breaking down, and not delivering, why did he garner interest from 3 other clubs prepared to give him his minimum ask? One club signed him for more than his minimum ask - good luck to him.
With Gagai, his experience, his position, and relative health, combined with the chemistry he has been building with that whole left side, you have to consider, is a 2 year deal really gonna be such a risk to the club? Particularly when there is no real obvious replacement currently within the ranks.
With Cody, one could argue (and Greg Alexander and Braith Anasta, and Mick Ennis have done exactly that) that Cody is the one behind the play, the potency, the threat of the whole Souths attack, and is the most key player to almost all of that being unlocked. He started 1st grade relatively late (26), hasn't gone through the physicality that someone like Adam has endured, and with Cody, it's not so much his speed is the key, it's his vision, guile, and ball playing ability that is keys to that play. That just doesn't drop off a cliff just because he is 31, or 32, or even 33. Cronk was still able to do that @ 36.
On Sutton, he had a major decline toward the end of his 5 year contract, and hadn't really been a dominant player for a number of years. This, plus the money he had been on, plus the cap situation with Sam, and GI, Adam etc, meant no way he was going to be offered big or long term deals. At that time, many were hoping he'd just retire. He started taking one year deals, because it's likely no one else would off e r better. To his credit, he completely turned around his impact and form during those one year deals. It's just not comparing apples with apples when talking about Sutto and Reyno contract positions.
