Definitely not the NFL, too much of the economy depends on the NFL, and like everyone else has been saying, they will be coming to an agreement at the end of this week.
NBA - Yes, they're probably going to be missing a season, and I think it will create at least a disinterest of a lot of people for at least a few years. I know with the NHL lock out it had affected me,I used to be a Rangers fan and I'd go to games here and there but after the lock out it wasn't until last year until I actually started watching NHL again, and still now as I watch it I don't even watch it as much as I used to.
I hope it doesn't happen to the NBA, but it looks like it's going to. It's amazing that these players make so much money, but the owners of the teams have been losing money for so long. Doesn't make sense.
