I don't understand what or whose hindsight you are referring to here. It sounds like you are implying the front office just lucked into a good trade, but to me it's just evidence they know what they are doing way more than we do.
Maybe they will make another big swing trade, or maybe they will make 1 or 2 small fringy type moves. If they do the latter, it wouldn't be some failure to "go for it". I trust the front office to do what's best for the team and sometimes that is doing nothing.
