how the hell do you use the player roles!!!!!!!!!!!!!!!!!!!

completely lost!!!!!!!!!!!!!!!!!!!!!!!!!!!

If you never learn how to use it, it still won't hurt your chances.  Don't sweat it.

I'd like to know what the hell that's all about too.

Player roles lets you rank players based on a formula that you create (for instance, if you value speed and could care less about shot blocking or durability, you could weight your formula so that it looks more at the former while ignoring the latter. You can also save multiple formulas (say, one for PG, one for SG, etc.). When you apply the formulas during recruiting, the recruits that match your standard rise to the top of your list regardless of what their overall rating is -- theoretically, it saves you the time of having to go line by line through the search screen judging for yourself which recruits best fit your system as you had to previously. 

Unfortunately, there's no way to work potential into the formula in player roles, rendering the feature all-but-worthless in my opinion (it has minimal use still, but I'm honestly not sure it's worth the hassle it takes to develop and tweak the formula(s) when it comes down to a cost-benefit analysis). Basically, you're STILL going line by line through everything to evaluate who best fits your system...you just have the luxury now of also knowing who starts out there pre-potential and can evaluate them first. 

Good concept feature in my opinion, just not developed to be very functional yet. 

Very good explanation.

I don't see how it helps recruiting, but I suppose it could help determine which player to play at which position, assuming that the values you choose to favor for each position are actually, you know, valuable in the engine for that position...

I would only use if if I couldn't use FSS....maybe I need one more player but I'm short of cash and can't scout more states.  But, realistically, I probably won't use it at all
