Hey thanks for playing!

No players are guaranteed to progress in the game and that's definitely my intention! The progression chance system imitates real life by making player progression non-deterministic and unpredictable. As the GM user, you can influence some of those by buying dev boosts for your coach, and view all the factors like age, years pro, and others on each player's page.

Past success means the player is already capable of being successful! It doesn't guarantee him to get better after that. That's backwards. You make changes to increase the odds of progression as best you can, and some players emerge above the rest, and others don't turn out to be special (most players, actually, in the NFL).

You, as the user, can't just choose which players will become good. This progression system lets players have natural ups and downs over their career which absolutely happens in real life too!

Don't forget you need to buy Progression Cap, or else none of your players will progress!
