Very interesting. It's a positive for the league from a credibility stand point amongst casual and hardcore fans.
I'm not aware of what performance gear (if any) Mitchell and Ness produce, so it's interesting they'll be responsible for the on-court apparell.
They are also a "trendy" casual clothing brand, so it will be also interesting to see what the jersey designs look like and how/if bumper sticker style sponsor logos will be used this season.
It sounds like clubs (like the Wildcats) will still be able to produce their own T-shirts through their own supplies.
I also think "cheaper" jerseys aka replicas, will be produced and sold around the current $60-$90 mark.
I'll happily pay for a Mitchell and Ness "premium" style jersey with higher quality - similar to what they offer with NBA products.
I also wonder what this means for heritage round throwbacks and distribution.
