We need to remember, this may not be true for Haliburton, but it's true for Tatum that he played until the last game of the season, so he could be a little tired, and while he is still young, he is not getting any younger, so resting him during the games they know they are winning is important. If you keep him playing at all games then he is going to either get super tired and have a bad start for the season, or he is going to even get injured as well. This is why I suggest that they are doing the right thing with him.
Haliburton was injured for a while too, which means that resting him isn't a bad choice neither, if he is back then he can get some minutes at times, to you know gain some momentum going into the season, but if he doesn't play much that's still fine. Plus this was just one game, we still don't know how it will go, maybe next game they will be the most played players, maybe they are rotating between games, we have no idea what they are planning.
People are making too big a deal over it honestly. The goal is to win games and ultimately gold. If th a t means playing some players over others than so be it. Seeing the game play out I think the right rotation was in. Durant was lights out, lebron was needed for his physicality, guards to spread the floor and defense from jrue. Next game someone else won't get playing time, no big deal. You need to keep a decent sized rotation you can't play everyone minimum playing time.
Well, that's how the media is making money. Making dramas out of small things like Tatum getting benched, and with how the people from social media reacts, I expect some memes coming from them that will be posted online (like a triple-double in claps, high-fives and the number of glasses of Gatorade he drank).
Anyway, I don't see this one as a big deal as well. In a roster filled with superstars, there's always a possibility for a player or two to get benched or at least play with limited minutes. In this case, it's Tatum in their first game, but I believe Coach Kerr will let him play in their next game against South Sudan. Speaking of South Sudan, we've seen how they played against the US team, but I don't think that it will happen again this time. As for this drama, let the media cover it. It will stay popular for about 3 days or a week at max then everybody will just forget it completely.
At the end of the day, like @wheelz1200 said, it's all about the Gold Medal and not whether you play many minutes, or not.
