so, looking at the schedule and standings, Canada is 4 points up on Mexico and USA, who are 4 points up on Panama and 5 on Costa Rica. One team is out at 5th, 4th has the play in, and top 3 qualify. CR hosts both USA and Canada and visits El Sal. 3 competitive matches but they could win them all given the venues? Still, tall task, and Canada can help USA by taking a point or three. Panama hosts Honduras (win), then visits USA before hosting Canada. USA I think advances with a win at home, and qualifies with a win and CR dropping points when hosting Canada or the USA. Getting any points at Mexico helps. Drop points to Panama, then things get interesting and may need a point in CR.
