Could this be the next Frank Sinatra?

Not even in the ballpark. For 16 he has some talent but control, not so much.

I'm not talking about his talent or his lack of control. For crying out loud, the kid is only 16. I'm referring to his distinctive voice, how very similar it is to Sinatra. Give the kid some more time to mature. Does anyone have a recording of Sinatra when he was 16 for comparison?

Boring as hell. He doesn't seem to understand the lyrics - Sinatra does. He might mature but I doubt it.

there's possibility's here but unfortunately everything is looks today. He has an idea how to sing a song. That's more than I can say for most of the so called pop stars of today.

"For crying out loud, the kid is only 16. I'm referring to his distinctive voice, how very similar it is to Sinatra.”

No, it’s not. Nothing that I heard, based on your link, is even remotely reminiscent of Sinatra. With a lot of work...maybe Jim Nabors.
