Not sure if there's a minimum amount that need to be cut, but you need to use at least 3 picks in the draft (including rookie upgrades)
We have already upgraded Thomas and Cox. And unlikely to trade pick 6 unless Tomlinson is still on the radar. Technically we could be finished already!!!! Unlikely though.
Possibly delist/rookie Sier?
Possibly delist Oxley (contracted?)
Possibly delist Blair (contracted?)
Possibly trade Fasolo (looks likely to stay)
