Their philosophy (avoid 9 figure deals) works if they can scout, acquire and develop cost controlled players, and assess minor and major league talent (internal and external). Marco Paddy is the primary positive on that front, and the Sox handcuff him.
Hence the team has little depth, outbids everyone on old players at the end of their careers, were forced to pawn their 2016 quality pieces for the few quality young players, and have seemingly permanent holes in RF and 2B.
Free or inexpensive "little things" like proper defensive alignment, proper plate approach, quality opponent game plans, proper baserunning, making correct throws (cutoff) and other basic baseball fundamentals would go a long way. It's why Cleveland, Houston and sadly the Sox are where they are in the standings.
Hahn said last October the team acknowledges shortcomings in fundamentals and areas of analytics, and he and the organization were committed to evaluating and improving in 2022. The team became worse in just about all aspects of baseball fundamentals this season.
