Question

Which one is more sounds natural?
1. People like you shame all other teammates.

2. People like you are a shame for all other teammates.

Answer

1. doesn't sound natural and would be improved by writing "People like you shame your other teammates.

2. Is wrong : "for" doesn't work here  and should be omitted. Substitute "your" for "all" as above and you can't say "you are a shame" here you should just say "you shame".
