If I read this correctly does that mean players no longer progress after four years? And also, I like the idea of this tool preventing the ridiculous regression in the game itself, but I don't think it can prevent a QB losing 6 overall in his 10th year, but merely replaces lost points?
The way I understand from reading so far is that a player in week 1 year 1 gets assigned a potential through some formula including the dev traits. The difference between their current rating and that potential results in skill points (similar to the XP points from the default game?) that randomly get assigned 3x per year through years 1-6 according to probability? How is the potential determined? Do all players (assuming they're rookies in year 1) reach their potential? In Year 1 of a franchise, will a player who is a rookie develop more than a player who is already in 3rd year?
Just in general, what is your main issue with the XP system, how is this better and what should we notice different when we start using it?
