Huh? By my count every single one of those teams went through the entire preseason and first couple months of the season (there is a lot more practice early in the year than late) with 10 scholarship players.
2015 had 10 recruited athletes until the middle of January when Suliamon was kicked off the team.
2010 had 10 until Czyz transferred in the middle of the season (and they had Seth Curry too, right?).
2004 also had 10 until Michael Thompson transferred, also in the middle of the season.
2001 was loaded with players!! Are you forgetting about Dahntay Jones or perhaps Reggie Love? By my count, that team had 12 D1 level players (13 if you count what guys said about the quality of JD Simpson)
Recruited scholarship players on the 2001 team:
Starters -- Battier, Dunleavy, Duhon, Boozer, JWill
Subs -- James, Sanders, Buckner, Horvath (injured midway through the season), Christiansen, Dahntay Jones
Walk-on who was D1 level talent -- Love and maybe JD Simpson
If anything, you just made a fairly convincing argument that we need to bring in 2 more scholarship players (which is what we are clearly attempting to do).
