Zion Wlliamson's rookie season is arguably the most anticipated since 2003-04 when an 18-year-old LeBron James burst onto the scene.
It didn't take long for James to deliver on the hype and a dozen games into Williamson's career, it once again appears the buzz was well worth it.
On Tuesday in Los Angeles, they'll meet on an NBA floor for the first time.
Williamson, the generational cinder block of a forward who at 19 years old often looks like the biggest physical matchup nightmare in the entire league.
James, the transcendant reimagining of a forward who at 35 years old continues to evolve and introduce new wrinkles to what's already arguably the most versatile skillset in league history.

They'll meet twice in one week and many times after, but this first meeting will always stand still in time as a message in a bottle moment, a first-of-its-kind clash sure to usher in memories of a fresh-faced James from 17 years ago and conjure up fantasies about where Williamson's journey will ultimately lead.
But while the circumstances of the eras in which they entered makes this a largely unprecedented matchup in terms of build-up and coverage, we have been down this road before. Here's a look back at a few of the NBA's notable first matchups between rookie sensations and established superstars.

For their career, O'Neal holds the edge in the regular season with a 17-11 record in 28 games played whereas, in the postseason, Olajuwon held the 5-3 advantage including a 4-0 sweep in the 1995 NBA Finals.
