Game manual or wiki

[dewguru]

New to the game.
Started a new career league, and right out of the gate, I've the option of customizing my head coach.
There are a lot of fields here, some that I'm comfortable guessing their meaning, others that seem vague overall.
Which left me wondering if there was a manual or online wiki that covered the different ratings and what they mean and/or their impact?
I've searched a few terms here in the discussion forum and searched online, but haven't found anything.
