Someone brought this sentence to me as her topic sentence for a paragraph: "Team players can cause success in their group." The moment I read it, I thought there's something unnatural about it. Then I said she could improve it by other words because we usually use 'cause' to talk about negative effects. I suggested:
Team players' performance can lead to their group's success.
Team players' performance can bring about achieving success in their group.
Team players can bring their group success.
I want to have a native speaker's opinion on that. Does her sentence need any improvement? Can any of the sentences I suggested be considered as an improvement?
