#1 - Athletic Dept in the black due primarily to YUM Center deal. Plus they already have a fairly new stadium and facility.
#2 - Don't know their Title IX situation and they already have an ACC Women's lacrosse team. Not sure what women's sports they could add, but currently ND HAS 3 men's sports that UofL doesn't have (hockey, M lacrosse, fencing) so you would think they could make room - but I just don't know
EDIT: Quick look at sports offered ND vs UofL:
ND has 3 Men's sports that UofL doesn't have
ND and UofL have the same number of woman's sports:
ND has Fencing, UofL doesn't
but UofL has Field Hockey, ND doesn't
Just by the number of sports offered, it would appear that Louisville should have room to add lacrosse under Title IX
By my count, ND is offering 35.1 more men's scholarships than UofL
UofL is offering 7 more women's scholarships than ND.
Assuming ND is in Title IX compliance, then Louisville should have 28.1 scholarships available to men (35.1 - 7 = 28.1)
#3 - As I mentioned above, their club team has been winning conference championships. The area is becoming a new hotbed for lacrosse and there is already a Div I lacrosse team in the city with Bellarmine
