but if you sell him at 32 or 33, won't you get back the same amount that you would get from a similar old fart you bought?
So, depending on how you acquired your player, you might end up with a net profit when selling your now old fart. plus you would save on all the price differences between the old fart you sell and the slighty younger, but still old fart that you replaced him with. Add up all those cost differentials over the ~10 seasons you could keep your home trained guy and you have money for higher average salaries, more arena, buying some younger guys.
