I used to use the default roles with stamina and durability removed (so technically I had to create it). They're pretty decent at giving you a general idea about who is good and who should play where.
Now that I'm more experienced though I prefer to use specialized roles instead of all-encompassing ones. E.g. Distributor, perimeter scorer, inside scorer, perimeter defense, inside defense, etc. Doing it this way makes it easier for me to organize my lineups to try and keep them balanced.
