Sheridan gets lauded as the only captain who achieved a victory against the Minbari, though it's possible that the propaganda that would've followed him kind of enhanced his image and drowned out other achievements. Still, if an entire EA fleet gets wiped out while only fragging one or two Minbari Sharlins, then while enemy capital ships were destroyed, you can't exactly call it a victory for Earth. With those kinds of losses, you couldn't really even brag about the enemy kills publicly no matter how you marginalized the enormous losses your side suffered.
"Through the brave actions of the 4th Fleet, two Minbari warcruisers were destroyed off of Orion II. Unfortunately,all seventy-four warships of the 4th were lost BUT IN OTHER NEWS Vicky Spears has shaved her head in an odd twist of rehab failureblahblahblah..."
Since that would've been the mode for the war rather than the exception, Sheridan's nukage of the Black Star and his living to actually tell about it would naturally get center stage for considerable time.
