College Hoops 2K8 Unlockables
This one is a great file and has a lot of depth in appearance edits, coaches named, and all classic teams. The one drawback is that it has the Team Name Glitch where some teams have their names cut short because coaches were edited in in Edit Team instead of Coach Profiles.

PS3 Roster without Teams Name Glitch
crques roster with coaches named & rotations set (ps3)
Here are two different versions of the same file. I don't know which is better or more up-to-date. I don't think this file is quite as deep in some ways, but it doesn't have the Team Name Glitch.
RAZRr:
RAZRr1275's PS3 Choops Rosters
All of these have different advantages. I think it just depends on personal preference.
