I think if he wanted to have a romantic relationship with you, he would probably be inviting you to a lot of things to the point where there is no doubt that he is trying to spend as much time with you as possible. Asking you to meet him at a game at the last minute might just be because he thinks you are a friend and doesn't want to go alone or someone he was planning on going with bailed and just one invite seems uncharacteristically uninterested for an ENTJ with a crush, especially one direct enough to tell you how pretty you are.
I'm always a really good friend and there when people need me, so you'll have to be a bit more specific before I'm going to say if this means anything.
My first guess is that he is not interested in dating you, but you probably have ground to test this theory a lot more. Invite him to a bunch of different things, including things where you two will be alone. If he is interested, he will probably go to all or almost all of these invites with you and there's a good chance he will make a move if you two are alone and he wants to make this happen.
I recommend you make it somewhat obvious that you are interested in him. The beauty of an ENTJ is that if we are not interested, we can just take it as a very high compliment and continue to be friends with you without feeling too awkward about anything. First semester in college, one of my friend's friends was interested in me and I was not interested and never asked her out, but she is one of my best friends now.
