Sometimes they do. You have two major commentators for sports.
Analysts, which do break down plays, but usually during breaks and halftime/intermissions because analysis takes longer and is HARD to do in real time.
Then you have color commentators who call the game live and are really there to fill the dead air and bring excitement to the broadcast. Their job is not to do analysis, it’s to call the game in real time and bring excitement to it.
In regards to Jomboy, his videos are great and in depth, but it takes a few days after something happens for him to get that video out. In depth analysis like that is not something you can do in real time.
If you want analysis there’s a ton of it out there. Just not in real time.
