Tom Kim captivated the PGA Tour as golf's best young star at 20 but how high is his ceiling?

There's a world in which Kim is probably a bit overvalued right now with his top-20 ranking

Can the toast of the fall become the major championship (or elevated event) debutante of the spring? That's the question when it comes to Tom Kim, winner of two post-Open Championship events on the PGA Tour and individual champion (if there was one) of the Presidents Cup in September.

Kim has captivated pretty much everyone who encountered him with not only his buttery approach shots and deft short game, but an electricity that is rare in the golf world. His aura, it seems, is nearly as singular and nonreplicable as his game. 

He is, without question, the best youngest star in golf. The 20-year-old (he won't be 21 until the U.S. Open at Los Angeles Country Club) is ranked No. 15 in the world and on the radar of even the very best players in the world.
