I love questions like this that force me to do research. Since 2000 (the last 25 seasons), these #1 picks have played in a Final Four:I wonder how many times this century the #1 pick has been somebody who played in a F4? Oden. Davis. Rose. Did Blake Griffin play in a F4? KAT? Crazy how rare it is.
2007: Greg Oden
2008: Derrick Rose
2012: Anthony Davis
2015: Karl Anthony-Towns
2022: Paolo Banchero
Contrast that with the 80s and 90s, when twelve #1 picks (over 20 seasons) played in a FF:
1980: Joe Barry Carroll
1981: Mark Aguirre
1982: James Worthy
1983: Ralph Sampson
1984: Akeem Olajuwon
1985: Patrick Ewing
1988: Danny Manning
1989: Pervis Ellison
1990: Derrick Coleman
1991: Larry Johnson
1993: Chris Webber
1999: Elton Brand
