He spent to his limit, saved on FA costs by paying just $40M for Gray & Contreras combined. Suarez looks like a good contract, especially when you couple it with the Durbin, Monasterio & Seigler deal, as Bregman and Harrison costs more than Suarez, Durbin & Co. He spent $6M on IKF and traded some scraps for Oviedo, but expecting him to add Alonso or Cease for IKF's money, or someone else via trade is rather picky and extreme.
Yes, some holes were left, but Brez filled 3 major holes very well and 3-4 moderate ones pretty well, and considering what budget and trade assets he had, he seemingly used them very well.
Did you want him to trade Tolle or Arias? Spend more than he could?
Without using hindsight only reasoning, explain how he gets Schwarber or Alonso with the same budget. Who do we not add instead, and wouldn't that be a new hole created?
