Victor Wembanyama mania is in full effect -- the future No. 1 overall pick in the NBA Draft was mobbed by fans as he touched down in the U.S. on Monday ... and the scene was crazy!!
The 19-year-old French phenom is at the center of the basketball world ahead of Thursday's festivities ... and all signs point to the San Antonio Spurs taking him as soon as they're on the clock.
Wembanyama immediately got a taste of what it will be like to be a celebrity in America when he landed at JFK airport .
