first lorenzen wright boosting sales or not is an impossible thing to figure out until you see a memphis grizzlies season without him, which has not happened until this year.
second, you bring up a strong, valid point. most of the marketing for games and tickets revolves around the star players on other teams. its an understandable appraoch as big names coming into memphis should sell some extra tickets, but i agree the focus is off. the first season or two it was about the rookies (pau and battier, drew gooden). they should probably focus more on rudy gay this year than the other teams.
the marketing definitely needs work, but the problem of filling seats for games has a much deeper answer than marketing strategies.
