@tsarstepan,
In all seriousness, it's probably a cultural thing.
Your sports seem to be all based around television and advertising slots, as far as I can see. The two main reasons that Football will never make it in the US is that..
1. The TV Channels would never tolerate 45 minutes of uninterrupted sport. A whole 45 minutes without an ad break,
and..
2 The American audiences have been raised on short bursts of sport followed by trumpet majors, dancing girls and peanut vendors for a few minutes, before another short burst of sport.
It is therefore my contention that you no longer have the attention span.
Put one of your padded giants from any NFL team onto a rugby pitch, take away his corset, padding, helmet and knickerbockers, and he'd be gasping a submission after the first continuous 40 minutes of play.
They're fit to a certain extent, can hit hard but not probably any harder thsn a rugby player, and they can run around and block people for a period of ten seconds.....but that's about it.
The excitement of an NFL game goes into schoolgirl squealy overdrive when a team gains a whole 20 yards.
In football, the ball can go to one end and back in a matter of seconds, and this can be kept up for the majority of the game in quite a few instances.
I know it's very hard to keep up with, after watching NFL, but if you gear your brain up to speed you could then see what the rest of the world gets so worked up about.
Don't get me wrong. I'd love to go to a major baseball or NFL game, but I would be going there for the spectacle and novelty, rather than the quality and pace of the competition on the pitch.
