I can see what subs came in. Most of the time they wait kneeling before the scorers table. Even when they don't it's always clear to me as to who came in and who left. I can also plainly hear the PA when it comes to fouls and some subs. I keep a mental tally on fouls as well. As for missed calls, well, that to me is the most self evident. And don't blame the announcers when the producer misses camera.
As for steals and assist totals, if I have wait for the half to get those numbers it's all good for me. Generally I can tell who is doing well in those areas just by watching the game. I'm not a real analytics person and I don't need those numbers immediately. I'm more interested in the score, the demeanor of the players, are these teams playing hard, what kind of offense are the teams running, what kind of defense, which players on either team look like they came to play and who not, the flow and pace of the game, things like that. That pretty much tells me all I need to know. Maybe it's not enough for others , but it is for me. For me announcers can't detract from the things I'm looking for. They can really only add to it.
