A post player who can score and defend consistently against Cardoso or Betts is, by definition, an All-American and a WNBA lottery pick. Dorka, Olivia, and Aaliyah were not at that level until almost the end of their college careers.
For that matter, neither were Cardoso or Betts. Do you remember Cardoso at Syracuse or Betts at Stanford? UConn played Syracuse in the NCAA Tournament in Cardoso's freshman year, and she was not a big factor in that game -- in part because she was not in physical shape to play major minutes.
So please don't expect Jana, Gandy, or any other post whom Geno recruits out of high school, Europe, or the transfer portal to play at that level in her first year at UConn. That will not happen. The BEST case is to find someone who can reach that level by the time she leaves Storrs, and is motivated to do so. That would be the next Stef Dolson or the next ONO, which is the most that UConn fans can realistically expect. And with UConn's talent at other positions, that should be enough to contend for a National Championship.
