No. They were never going to acquire 2 quality SP this offseason, unless a great deal fell into their lap they couldn't refuse. They have Wicks, Assad, Wesneski, Smyly, Brown to fill the 5th spot. Doesn't make any sense to block the young guys that are decent assets. They might sign some cheap depth SP flyer to compete for the 5th spot. They chose to bring back Hendricks over a more expensive upgrade.
They had 1 SP to fill to replace Stroman. They could have signed Snell, or Montgomery, or traded for Bieber etc. They chose Imanaga. They went for the cheaper value signing. They're likely trying to squeeze under the CBT cap again.
They've got about 35m under the cap to spend right now. Enough for Bellinger, a couple of decent pen arms, and another cheap corner/DH bat. We're probably not getting Hoskins unless we miss on Bellinger or Ricketts is ok with going over the cap slightly.
