UA is bailing on the college sports team market, which is why ND will be looking elsewhere.
There is a long and interesting article on The Athletic site about the situation ND now finds itself in. For those of you who have a subscription to The Athletic, it is an interesting read. One of the interesting things it discussed was allowing football players to do their own shoe deals, much like is done in the NBA right now. With the ND brand still as strong as it is, that might be an interesting way to attract recruits with NIL money, instead of having the school-attached collectives ponying up that money. Swarbrick is a fan of NIL endorsement deals, but he isn't very fond of the collectives, so maybe that is an option he will look at seriously. Could be a Win-Win for ND, not just in football, but in other sports as well.
Aside from Nike and Adidas, there is some discussion in the article about ND going with an upstart company, such as Lululemon. I am an old fart, so that name isn't familiar to me for athletic apparel, but maybe that is a brand more familiar to the younger set.
