ESPN+ is what ESPN uses to trick you into giving Stephen A. Smith even more money. I strongly urge everyone not to be tricked into giving Stephen A. Smith more money.
If you have ESPN+, you just need to go to watchespn.com, it's in the basketball section and near the top since it's a live event. If you don't have ESPN+, a link won't help. It will kick you to an ESPN+ login prompt.
