What are the most notable collaborations of MacKenzie Alexander in the sports reporting field?

I'm sorry, but the available content doesn't directly address the most notable collaborations of MacKenzie Alexander in the sports reporting field. However, I can share that MacKenzie is the host and founder of All Bases Covered with TDT Media, a platform where she focuses on the real and good in athletes and coaches, allowing them to tell their stories.

Would you like to know more about her work with All Bases Covered or her approach to sports reporting?
