Namibia vs United States
So in these two teams United States of America teams is much better as compare to Namibia team. Because United States already played with Canada and Netherlands. So Namibia is looking a weak team against them. By the way this is too early to say. Match will start in 15 minutes. United States won the toss and they decided to bowl first and I think they made a good decision they will see the target and they have a goal so they will chase easily. So let's see.
I would disagree with your opinion here that the United States of America as a team is slightly better than Namibia. It could be said that United State of America has played a bit better recently in some matches but ultimately Namibia is better than United State of America as a team. We can understand this only if we see the ICC Men's ODI Team Ranking.
But talking about today's match, Namibian team is not doing very well as they managed to score only 144 runs in 38 overs and lost 5 wickets already. On this performance I don't think they can cross 200 runs. So it can be said that United State of America is more likely to win this match.
