Sure, but it's a lot easier to make those moves when the farm is stacked and the core players are young and set. That was not really the case when Ben became GM.
Additionally, Henry decided to open his wallet for Dombrowski to sign an aging pitcher to a huge contract, a luxury Ben didn't get.
I know I'm in the minority, but I'm not impressed that Dombrowski was able to get Kimbrel or Sale or Price.
