It would be nice if it was possible to see which players started their careers at a certain team, would make it easier for people to follow their ex-trainees as well.
you can already see that since they mention where a player was drafted. and if you want more information, you can see it when htting the player history button (let's you know if it's superior statlines, when it joined U21/NT, in which season they were sold and to whom, aswell as Allstar participation & MVP voting results)
So isn't that feature already kinda available?
