Dempsey is not one of the 50 best players in the world, and it has been a long time since he has been in college, and just now he has hit his peak as a player.
The play in a professional designed youth system before they become professionals, and even then they play on B teams weekly so their development contains plenty of game time, not just practice time. What the NBA would need to do is instead of the NBADL, they would have to expand the NBA rosters to 25 players, and have the back end be a D league with a regular schedule.
With how it is structured, I understand throwing a player into the league may not always be a good thing, but there is a better system that can create better basketball out there, they just dont want to pay for it. free labor and some level of development from college is seen as a better fit.
Enough writers in England think he was good enough to be voted as Footballer of the Year in England for his play this year in the Premier League (which is a top 2 league in the world) that he came in 4th in voting.
I don't know how you would rank players in soccer, considering it's even more subjective than basketball (due to the variety of positions and lack of meaningful statistics for a variety of positions) and there are vastly more pro soccer players at a high level. I don't necessarily disagree that he isn't a top 50 player. Taking out keepers, that would mean he was, likely, top 5 in the world at his position if he was a top 50 player.
I'm not sure where he is without watching him on a top 10 club. If you were to ask if he was a top 50 player in the EPL, then the answer is yes, and likely much higher.
In the end though, the point was he went to college and I think he is good enough to be mentioned. I was pretty clear in stating he was not the best player.
I mostly agree with everything else, though Soccer and Basketball are very hard to relate to each other in terms of development. I think it comes down to where the best coaches for development are for that sport. In basketball it is college, not the NBDL. In soccer it is at those feeder clubs.
