Bench is a little light on experience. Sure, there's Cairo. But the rest of the bench is relatively inexperienced.
Wouldn't be shocked to see the Reds replace Nix, or possibly even Heisey, with an experienced bench player.
Matthews Jr. is a possibility. Or someone in a trade.
The Izzy/Springer moves indicates to me that Walt wants some more vets for the stretch drive. The bench is an obvious spot for it.
