Either staying put or trading up would be a risk, and that's the nature of a risk I guess. You'll always regret the wrong choice. If we trade up for McCartin and he turns out to be a dud, and Lever turns out to be a 250 game backline general, I'll be massively pissed.
Yet Lever could have constant knee injuries whilst McCartin becomes a star. Massive risk either way know. Don't think we can take the risk again of going to short in a finals series.
