The downtown of every big city is dangerous, more so when hooligans get swept up in sports matches. Local law enforcement knows that and will be increased to try to handle potential problems. But obviously caution is needed.
I don't like mass transit at night- especially to a championship game. If it was my son, I'd advise a cab.

Thanks GG! His hotel is near the convention center and the river, so I did advise a cab a bit ago since the game starts at 8:00 and will be over pretty late.
