Do you know anyone named Trevor?

My sister and her husband just found out they are having a boy and the name Trevor has shot up to the top of their name list

While its not a completely retarded name like we see a lot of parents name their young sons these days(names that mind sound cute for a baby boy but will get his arse kicked when he becomes a teenager), I still don't like the name for these 2 reasons:

1. Every Trevor I have personally known has been a loser or douche bag.

2. Not many famous people named Trevor. You have Trevor Hoffman, Trevor Daley, and that's it. Not many people named Trevor ever amount to much.

3. It just sounds like a beta name. This ties back into point #1, the loser Trevors I have known have also been betas.

So what is the best way to convince my sister and her husband to go a different way. The downside to that is they could go even further in the wrong direction, and name their son something REALLY beta like Keylee (a person in our office who just had a son named it that. Yikes)
