duffey's stuff has ticked up this year and he's a legit no.3-type at this point. he's a flyball guy and will give up his share of gopher balls, but the guy can miss a decent amount of bats and is proving durable. think scott baker for a comp stuff-wise, but hopefully not durability-wsie. he'd be knocking on the tail end of any twins top ten list i did, even with our stacked system.
