I definitely agree that Hoyer knows how to put together a bullpen on a budget. However there is a major drawback that I think gets overlooked and it's the fact that it usually takes a month or so to really get the bullpen set. You basically end up with a few guys producing significant negative WAR in April/May while things are getting ironed out. You are always going to have bullpen arms battling out for spots, having to deal with injuries but it's a nice luxury to have only a limited number of spots up grabs instead of piecemealing the entire thing.
On the offensive side, we have Cassie, Ballesteros, and Alcantara that need to either play or be dealt. Maybe you move one before the season starts? I think the young players give you some flexibility on the offensive side to wait until the trade deadline to address any needs instead of being forced to do it in Free Agency.
I would like to see a big upgrade with the bench, especially in the "Justin Turner" role. On the pitching side, we should have plenty of money/assets to acquire 2 TOR type pitchers and a couple of established arms that aren't a Hoyer "project".
But like every year recently, it seems to come down to how much the Ricketts family is willing to actually open up the wallet.
