Yes, that happen's sometimes. Some guy in my league got frustrated with BB and before he quit, he fired all of his players (also some 95k Center). So I guess it's just important to check before each game if the opponent has got players on the roster. If not, you can still get full minutes if you assign players like
PG: A/B/B
SG: C/D/D and so on...
