Here are the rookie contract extensions from last year:
C.J. McCollum (Trail Blazers): Four years, $106,633,450 (story)
Steven Adams (Thunder): Four years, $100,000,000 (story)
Giannis Antetokounmpo (Bucks): Four years, $100,000,000 (story)
Rudy Gobert (Jazz): Four years, $94,000,000 (story)
Victor Oladipo (Thunder): Four years, $84,000,000 (story)
Gorgui Dieng (Timberwolves): Four years, $62,800,000 (story)
Dennis Schroder (Hawks): Four years, $62,000,000 (story)

I thinking that it will be between 62 mil and 84 mil.
