Make sure that the whole range of the ratings scale is used visibly and under the hood. For example in CBB 19 I didn't see one player with ball handling above 6. Every rating should have at least a few players who are a 10 in that skill, both in the scouting of that player and in terms of their actual ability.
Tying in somewhat to the request above, there needs to be more lower rated recruits who are specialists or elite in one skill. These players will also reach their potential in that skill regardless of coaching.
The scouting notes should not repeat themselves with the the same message week after week, nor should they be contradictory so often. Even bad scouts will have talk about the total range of players ability and be pretty consistency with their observations even if they misjudge a player.
Reduce the amount of shot blocking per game, especially blocked jump shots, and blocks by smaller PGs and SGs. There should be more missed shots categorized as heavily contested misses.
When the bench is automatically emptied during a blowout, the starters should not come back in unless the lead gets under double digits with more than a minute left in the game.
Immediate return of scholarship when a player goes pro, and grad transfers.
