I'd say there's a good chance MLS happens this year. NBA could happen but suddenly Orlando is the worst place to have it. NHL should be fine overall. MLB would be fine if the owners cared about anything other than their bottom line. NFL is probably going to happen but shouldn't. the contact sports are likely the ones to be most in jeopardy in terms of infection, so nfl, nba, hockey, maybe soccer in that order from wrost to best. mlb is pretty safe in comparison. in terms of timing, mlb, nfl,(when is the soccer season??) and nba/ nhl in terms of worst timing to best. i'd say its a pretty mixed bag really eta : but if I handicapped them the way I outlined them I'd say worst chances to best are nfl nba hockey mlb depending on mls's schedule, they are in the nba/hockey group I believe, but lower on the scale Soccer is comparable to hockey I would say but it's outdoors. MLS season is right now. for reference, they are playing professional soccer in Europe right now - in Germany since May 16. It's going fine. No fans.
