I'd like to expand the idea, so that well trained players below a certain potentail can experience an increase, to reward good training - that way bad potential players (and the draft is full of those) can become solid role players or even cornerstones of lower div teams.
Plus untapped players with high potential should retain their training speed, so even if sb. picks them up later in their career, we can still work with them.
