+1 ball for making me feel so smart.
its just like any economic market really. The transfer market has its peak periods where a player will be over priced.... and a player of a certain age will fetch a different value in certain times as opposed to other times.
there are good/bad times to buy/sell etc etc.
zyler is just taking it to that next level.
think about this example. All 18 year old MVP is going to sell for roughly the same (unless they have just straight up dodgy stats)... when it boils down to it, he has MVP potential....... But once he is 20/21, dependant upon how he has been trained, not all MVP potential players are going to be the same.
So, an 18 year old MVP has the 'potential' to be great, and hence is a better' guarantee' at high sale price, when compared to a 20 y/old MVP good but not quite so good MVP player.
Statistically speaking, if you took the average sale price of 18 year old MVP players, and compared the standard deviation (ie: the difference between cheapest to most expensive) and compared that to 20 year old MVP average sale price standard deviation... you would find a smaller deviation on the 18 year olds.
And thats how some people roll. They would rather sell their MVP trainee, than risk trying to train him, stuff up the training and then have to sell a partially trained 21 year old MVP.
Not suggesting that Zyler would stuff up the training.
but yer, lots of different scenario's like that. The fishy example that zyler gave is just the next level upon that example I gave.
