Lol, I was mostly kidding on those.
But still... I'd be really amused reading complaints in the main forums if it did get implemented. "Man... My star player didn't wake up again and is suspended for the conference finals." "Maybe you should've hired a phone user then?" Or, "My paralegal sucks.. why can't we get real lawyers?". & the notion of specialty named "Phone user" entertains me as well.
I guess technically it could be based off the hidden aggressiveness stat that already exists. Those with minimal aggression are passive (& susceptible to intimidation). Those with high aggression are not, but will also be thrown out of games & suspended frequently. Intimidation factor wouldn't be a new skill/attribute, just basically a counter to flagrant fouls then x5 for every suspension. (You wanted a visible counter, so assuming that was already there.) Gives you both a penalty & a counter-bonus to getting suspended. But yeah, not realistic.
