Red Sox fans should feel very fortunate. On the whole, we have been very successful since this ownership group took over, and we are set up to look very good for the foreseeable future. IMO, the team put together on paper has been a potential contender every year. Sure, there have been years when the plan did not work out, but I don't feel like there was a single offseason where the FO punted.
The FO is willing to spend. As you mention, they might not spend it the way the fans want them to, but they always spend. That said, they were willing to blow past the luxury tax this year. They will be working to stay under it next year, so that will limit them somewhat in their spending.
