Now that the business end of the season is upon us, there is a lot of anxiety and stress on the forum. Some of that may be due to the complexity and difficulty of the upcoming matches. I think it'd be interesting to see which team you guys/gals think pose us the biggest problems in any specific match. Feel free to choose "Other" if there is a match you feel where a team poses a bigger problem than the choices on the poll.
EDIT: Forgot to add, reasons for your choice can be technical, personnel, or fatigue... or whatever else.
