You might need to make up your mind here.
While no one has questioned the signing of Pearce over a reliever more than me, you were predicting he’d be worth a much higher AAV on a multi year deal.
And it still leaves other options. If, as you’re suggesting, Chavis can replace Pearce, you are in effect saying Chavis should produce equal to a multi year higher AAV contract player. Doesn’t that mean Chavis should have significant trade value? Maybe enough to trade for a reliever?
