Spark plug personality badge...can you tell the difference?

I haven’t really taken the time to do the experiment but is there a big difference between not having it and having it? I couldn’t imagine there being that big of a difference but then I guess what is the point of putting that badge in the game

Idk but i used to start PD JR and he played just ok for me. Once i started bringing him off the bench he became money

Sounds like 2k lol

Spark plug also kicks in after timeouts so if things are going wrong, take a timeout.
