Productive big men are staying in college a lot longer than the guards. Pretty easy to identify several dynamic frontcourt duos.
Gonzaga: Chet Holmgren, Drew Timme
Duke: Paolo Banchero, Mark Williams
North Carolina: Dawson Garcia, Armando Bacot
Auburn: Jabari Smith, Walker Kessler
Michigan: Moussa Diabate, Hunter Dickinson (I feel like Diabate will eventually start)
Texas: Dylan Disu, Tre Mitchell
Kansas: Jalen Wilson, David McCormack
Notre Dame: Nate Laszewski, Paul Atkinson
UCLA: Jaime Jaquez, Cody Riley/Myles Johnson
Indiana: Trayce-Jackson Davis, Race Thompson
Now, can the same thing be said about dynamic backcourts? I don't even know where I'd begin with the top backcourts. I'm certain this is wrong, but these might be my top 10 backcourts.
1. Kansas
2. UCLA
3. Tennessee
4. Gonzaga
5. Villanova
6. Texas
7. Kentucky
8. Oregon
9. Purdue
10. Alabama
