There is still two MLS Contest coming up after the international break. One for the 2 conferences finals two-legged series, the other for the MLS Cup single match grand final.
After, I don't know. One thing for sure is that I'm seriously thinking about taking the MLS Contest to the next season by starting at week 1.
Other than that, hockey would be the most interesting sport for me to start a contest. But it would have to be in an original format to motivate me going forward with it. Maybe something on a weekly basis where people choose teams and/or players.
Nonsport-related, a crypto-themed challenge would be fun. I'll have to think about it. :-)
