Personally, I find WAR dubious at best. Both flavors, although if forced to choose I'd use bWAR over fWAR.
But it's interesting none of those pooh-poohing this signing bring up WAR, where Bader was between 1.5 and 2 WAR better than Martin in 2024, depending on version.
Many of thise same folks throw around WAR regularly...when it suits their arguments.
