So if RSL wins tonight, the team moves on to the Western Confernce finals. If RSL ties, they move on. If RSL loses by one goal, they move on. If RSL loses by two goals, they move on.
If RSL loses by three goals, they go to overtime. And if that ends in a tie, they go to a shoot-out.
And if RSL loses by four or more goals ... well, we don't want to think about that. (Because that means RSL will be out.)
Oh, and there is another MLS playoff game tonight - Colorado Rapids at Sporting Kansas City (6 p.m., Fox Soccer Channel).
