I’m sure that Jimmie Foxx will rebound sooner than later. I’ve seen a few in my past few leagues among the league leaders in multiple categories.
I’m finding in my anecdotal experience that it’s better to have a batter that is elite in one area and lacking in others, than to have a “jack of all trades” type. For instance, my 77 Tony Gwynn is high 80s in contact (mid 90s against RHP), with good speed and acceptable defense, but no home-run power and a low walk rate. He’s won two batting titles and is a perennial 4+ WAR player. On the other hand, my 95 Live series Mookie Betts is mid-70s in just about every offensive rating, but struggles to reach even 3 WAR most seasons.
