Well, this is my final shameless bump for this post.
As predicted the sellout is causing the Mavericks to reclaim any unused ticket blocks set aside for groups. Anyone still wishing to get tickets for Saturday will need to contact the Mavs (per the original post) NO LATER THAN 3PM TODAY (Tuesday, February 23). After that time the unsold tickets will be released from their hold.
If you have been hesitant...today is the day!
See you there!
