It depends a bit on the player under 450k, but unless they’re really attractive, I’d go with option 1. Ziebell benefits from Hall being out of the side, and Walsh is a quality player who could prove to be a savvy pickup if he gets back close to his best.
Laird is a gun, but if he forces you into a compromised second pick, and especially if he means you need to use your 3rd last trade, I’m not sure he’s worth it.
