So not wearing pads = more physically demanding?
Sports like football, hockey or rugby require more strength. I think a sport like soccer requires more stamina (I hate soccer, but those fuckers sure do have to run around forever!). Hockey has just as many games, baseball has many more. Something like UFC, which requires strength, stamina, agility, and mental toughness, could easily be argued as more physically demanding than any of the major sports leagues. So what, exactly, makes basketball the most demanding league on earth?
Dude, I played 15 seasons of football. Saw many OL 6'3", 315 that could lift a VW bug.
Strength does not make an athlete.
What college football player can play in the NBA?
There are former college basketball players in the NFL that DID NOT play college football.
They are that good as athletes. They have to be.
Baseball?

UFC?

Man, you know nothing about athletes.
What UFC fighter played basketball anywhere?
Running 8 miles a game+ for 100 games in 7 months.
Soccer has to be in the top also but no where near as rough as basketball. Soccer athletes are better as a whole than football and I also do not like the game.
NBA is toughest league in all of sports. NBA is the HARDEST sport to make it in. HARDEST sport to play a full season in. Great players in college that do not even get drafted. Only 15 spots and most 2nd rounders do not make it. What other sport only has 2 rounds in the draft?
You need to get off the football kick. That was one of a number of sports I mentioned, and it was only for one attribute.
Why should I care if people in other sports played basketball? What effect does that have on this discussion? How many basketball players have played professional hockey? None? Well, hockey must be more demanding!
I only mentioned baseball in regards to the number of games played. I would never actually put it in a list of sports with the best athletes.
Are you trying to say UFC fighters aren't good athletes? Perhaps you are the

one. They need strength, speed, agility, and yes, even endurance. A championship fight can go for 25 minutes, and while that's not as long as most sports, it's a hell of a lot when you're getting hit. I imagine that's why the list someone else posted had boxing at the top, all those rounds of fighting.
I don't know why the NBA only has a 2 round draft. Are there a lot fewer players in the league than other sports?
I put the NHL above the NBA for hardest sport to play a full season in. Basically the same number of games and as far as I'm concerned easily the toughest playoffs of the major sports.
I'm not saying the NBA doesn't have good athletes in it. It certainly does.
