to generate that much interest or than many tickets sold because he's a local kid. There are several reasons for this IMHO:
1. Skylar came from a high school whose parents had no association with ND except for mothers who worked for housekeeping or in the ND cafeteria kitchens. Hardscrabble is a kind word to describe that portion of South Bend. Marian on the other hand is a private school catering to Granger kids. These people are more than familiar with ND and include many alum and administrators. DJ may change some minds about buying season tickets, but it won't be the first time his classmates and their parents considered it.
2. DJ was not embraced by his school the way Skylar was. For one thing his teams weren't successful. Washington made the state finals 3 years in a row. Marian didn't win a sectional. Secondly. I've heard stories that his teammates considering TJ selfish. Third, let's be honest. I doubt that 5% of the Marian student body was black, while blacks are the largest ethnic group at Washington. Marian has always had the reputation of being the snobbier of the 2 Catholic high schools here. There may be some change in that respect starting now that Marian accepts vouchers, but 10-15 years ago kids would be ostracized if there parents didn't make enough money or weren't otherwise important.
3. Skylar was really something special in the West Side community. I remember well when Jackie come from the same high school and with Parade All-American honors. There was not the same excitement or obvious increase in ticket sales to the West Side community then. Skylar's stepfather was well known and respected on the West Side. Everybody knew about her before she entered high school. And she was frankly the about the only thing the West Side had to be proud of for a while. Marian students and alum and local suburban families have their own goals and dreams apart from DJ.
4. Thee are some other reasons too, Tickets are 3 times as much for the men, there's some apathy about what Brey's teams can do (as compared to Muffet who won a title and generally produced a Sweeet 16 team). Also, Skylar started right away while DJ probably won't (although he may play most of the minutes like Eric did as a freshman.)
If DJ proves to be a great player, then he'll help attendance over his 3 or 4 years. But don't expect sellouts every game this year.
