a.) Playing a team you're NOT scheduled to play in any specific round. So for example, you and I don't play this round. But if we're both online and just want to get a practice game in with our league teams, we can still play. Just know that the game doesn't count.

b.) Playing a team you've already played once before the round ends. In this case you've already played the Bulls officially. Any games thereafter you play against the Bulls don't count statistic and record wise.

Neither of these games count.
Now, if you want thelonestranger want to play again, that's on y'all.
But if the pretenses were that you guys were playing a league game (and I'm assuming that this is AFTER he advanced to Round 4), it still counts because it was the first time you played in a set round.
