Harley's a perfect fit for every midfield.Merrett as as professional as they come. No chance he 'falls off a cliff' at only 31.
Hobbs and Tsatas are still developing, it's not like we rely on them. Having two players turning 31/32 as your best mids is far more worrying. (kelly, yeo)
Two players kicked 19 goals, they only need one more to reach your target Kako looks pretty advanced for a kid too, but wont play every game.
We don't have as many holes as you think. Especially with Reid, the main needs would be a key forward, one more small forward and a key defender IF Zach Reid can't get over his injuries. Harley is the perfect fit for our midfield, and thanks to getting Kako as a NGA one of our extra first round picks is almost like a bonus, so I am happy to trade our picks out for Reid.
If you don't have any decent key pillars you're going to struggle, no matter how good he is.
He isn't improving you from 11th to a flag. Nowhere near it.
