Mitch Wallis would be a really good option for us, I don't see him as A grade but a level above Bastinac and Bell, is he worth a 4 year contract though? I'd go with 3 with performance levers to trigger a 4th.
I think you've got to weigh up the full picture. If 4 years gets him over the line, then I'd make it happen. This is because free agency for us this year is a genuine free hit. It will only cost us salary cap and list space. We don't have to give the Dogs anything in return. We can get a decent player and still go to the draft with all our picks intact. This means you aren't taking as much of a risk as you would with a trade. Therefore, taking more risk with the contract isn't such a big deal.
While we have to be cognisant of the likely future salary demands of our more impressive youngsters, we also have some of our highest paid players likely to be finishing up in the next 3-4 years. I think we're in a good position to chase a bloke like Wallis a bit harder than we otherwise would.
In terms of our attractiveness as a destination, the last time I can recall a similar buzz around a young list is when GWS started to show their wares. There seems to be universal praise about what we're doing up here. Wallis, at aged 25, won't only be looking at 2019 potential but for the next 3-4 years after that. Assuming he and his manager recognise the potential of our list as the rest of the footy world has, then we'll be in with a shout.
I think we've got a really good package to offer him - a side with recognised potential, off field stability including a highly regarded coach, a clear need for a player of his type and the ability to pay him well over a long period. If he's prepared to move interstate and he isn't chasing immediate success, we've got to be close to the top of the list.
