Honestly id just be guessing. But id say they did what the Bulldogs did when Gus went there. Stack the team with proven guys to provide a base for the youth to work with. To get these guys you often have to pay overs when your team is a bottom dweller. Look at how much the Bulldogs had to pay to get Critta. It seemed crazy at the time but looks genius now.
The Warriors don't feel like a bottom dwelling team right now. So have that going for them. But personally i wouldn't be upset if they paid overs for a proven talent. Just not overs for Eels bench players.
