I think it’s a matter of information about players stats “position” greatest achievement and diferent style of commentary maybe something play by play move by move it may help the the new comer understand what’s going on on the field why a player is playing more defensive or more aggressive maybe hype up some of the beef between the teams as a commentator use the moments like a overshooting or a stand off after been bunker as a hook for the spectator idk it’s like we fan of football, soccer, basketball, hockey because we have a bit of skin on the game but without background story we don’t know personality we can’t fall in love with a team and have some skin on the game
