Taking a step back from the usual skepticism that is warranted with an addition like this, I am all for Madden finally (re)introducing a player morale/personality system in franchise mode. Something like this definitely contributes to the longevity and replayability of the mode (a la The Show, 2K). The past few Madden cycles I have not been able to enjoy more than a season or two into my franchises. This helps majorly if implemented decently and catered to with patches along the way.
Potentially able to scout (and customize in custom draft classes) personality traits of the upcoming class? Would be pretty solid if possible.
