Give Banks a go at it.Interesting idea, Olds. If we bring in a tallish role back like say Trezise to play #4 that frees Brown to play as a designated kicker, sagger, part-time mop. It could be that we have to develop Brown's defensive game and it's not viable to move him yet. (He's got work to do there.) But if we think we can get Brown right defensively 1v1 air and ground we should definitely look at this IMO. If it won't hurt his development.
Brown tested about 3.0/20m IIRC. But when he lets down (rare) he burns. I've been surprised. Short is pretty brisk. He uses his burst to get to position to receive. He's actually good at this. But Brown is equipped physically for the role.
The other bloke we might try here is Smith. He's not as advanced as Brown but has a future IMO.
It was all he did at the Devils - run to receive and then deliver off half back. Every single game.
