don't know which war the hall looks at (if at all) but he has 35.8 bWAR - crazy difference between his fwar and bwar mostly due to framing directly included in the Fangraphs calculation, bwar doesn't use framing.
playing in KC definitely didn't help him
in comparison, Joe Mauer fWAR 53.5!!
However FanGraphs formally incorporated pitch framing data into their Wins fWAR calculation in March 2019. Mauer retired after the 2018 season.
He's well liked but I never considered him a superstar type player - having watched pudge and mauer
