I mostly agree with what you've posted here. I am definitely wanting to see Bloom build a strong foundation and build that sustainability that he talks about repeatedly. The criticism that I have about Dombrowski is that I don't think we needed to get to this point. IMO, we could have accomplished what we accomplished during his tenure without going to the extent that he did.
Interestingly, I am one in the minority that really doesn't have a problem with the Sale extension. Like with the Beckett extension, if you don't extend early, you risk either losing the player or having to pay a higher price.
In addition to ERod's pending free agency, Bloom needs to consider Bogaerts' possible opt out in 2022 (I believe).
I am a very big Bloom fan. I, too, am excited to watch the process over the next couple of years.
