So assuming the C's win against the Bulls the Hawks take East Group C by way of winning the head to head tie breaker. That means in order for the c's to make the cup tournament they'd have to finish with the bets point differential of any team that finishes 3-1. The c's currently have a point of +14.
The four teams that are in it are:
Knicks (+15) and Magic (+37, play BKN tonight). Knicks and Magic will play Tuesday to decide who wins Group A.
Bucks (+29) and Pistons (+4, play IND tonight). Bucks and Pistons will play Tuesday to decide who wins Group B.
So, basically, if you want to maximize the C's chances of making the NBA cup you should root for the Magic to beat the Knicks and the Bucks to beat the Pistons on Tuesday, because they have higher point differentials to go up against the C's. Alternatively Knicks or Pistons winning i good only if they win by a BIG margin, to knock the Magic and Bucks point diff down.
The c's would ideally win by at least 15 tonight, that would guarantee them a better point diff then then the Bucks (if the bucks lost by even 1 point the c's would have a +29 to their +28).
So, to summarize:
1) Root for Magic loss tonight, the larger the difference the better to lower their point diff.
2) Root for Detroit to AT BEST win by 10 or lose, which will keep their point diff less than the C's current differential.
3) On Tuesday root for the team with the highest differential out of Knicks/Magin and Bucks/Pistons to win, because those teams will win their group.
Confusing? Yes, it is.
