Vince Young shows all the signs of being a sociopath. His particular flavor also shows numerous signs that seem to align with Narcissistic Personality Disorder.
For you Tacoma people, do you remember a guy named Dale Washam, who randomly got elected as Pierce County Treasurer, then cost the county millions in lawsuit settlements? Yeah, we're talking about the same kind of "leadership" influence. Google it and have some laughs (and some cries, real and local people are involved). As much as I like VY's talent, I just don't think the tiger can change his stripes.
Since I'm not a psychologist, that means I can say things that are obvious to most observers, without it being an "ethics violation"-because-I-haven't-examined-him. Life brought me a cornucopia of sociopaths over the last 10 years, and I'm getting all too skilled at noticing the signs. My ex-wife's attorney (Narcissistic PD), a nearly-disastrous romantic relationship with a sociopathic Borderline PD, and for several years dated gals whose exes were Narcissist PD's. I paid attention and noticed the patterns. The absolute BEST thing you can do with sociopaths is not to get into any significant business or personal relationship in the first place.
There's enough data out there to reasonably conclude that VY shows numerous signs of being a sociopath, most likely of the Narcissist PD variety. If you want to know what VY would be like in any kind of extended leadership role, Google the Dale Washam saga, though honestly, VY in a backup role wouldn't be able to do THAT much damage, but he sure would be a cancer and a divisive influence and distraction, and could single-handedly derail the team even in that role.
Some sociopath traits, from Wikipedia (ICD-10)
It is characterized by at least 3 of the following:
Callous unconcern for the feelings of others;
Gross and persistent attitude of irresponsibility and disregard for social norms, rules, and obligations;
Incapacity to maintain enduring relationships, though having no difficulty in establishing them;
Very low tolerance to frustration and a low threshold for discharge of aggression, including violence;
Incapacity to experience guilt or to profit from experience, particularly punishment;
Markedly prone to blame others or to offer plausible rationalizations for the behavior that has brought the person into conflict with society.
Does VY's publicly known behavior align with many of those? How about this list:
Symptoms of Narcissistic Personality Disorder, as defined by the DSM-IV-TR include:
Reacting to criticism with anger, shame, or humiliation
Taking advantage of others to reach own goals
Exaggerating own importance, achievements, and talents
Imagining unrealistic fantasies of success, beauty, power, intelligence, or romance
Requiring constant attention and positive reinforcement from others
Becoming jealous easily
Lacking empathy and disregarding the feelings of others
Being obsessed with self
Pursuing mainly selfish goals
Trouble keeping healthy relationships
Becoming easily hurt and rejected
Setting goals that are unrealistic
Wanting "the best" of everything
In addition to these symptoms, the person may also display dominance, arrogance, show superiority, and seek power. The symptoms of narcissistic personality disorder can be similar to the traits of individuals with strong self-esteem and confidence; differentiation occurs when the underlying psychological structures of these traits are considered pathological. Narcissists have such an elevated sense of self-worth that they value themselves as inherently better than others. However, they have a fragile self-esteem and cannot handle criticism, and will often try to compensate for this inner fragility by belittling or disparaging others in an attempt to validate their own self-worth. It is this sadistic tendency that is characteristic of narcissism as opposed to other psychological conditions affecting level of self-worth.
For comparison, Brandon Marshall of the Bears has "come out" as having Borderline PD, which often goes along with sociopathic tendencies. He's been honest about it, I would say courageous, and obviously worked hard to get better. (Most Borderline's would shoot the messenger and say YOU have it, not them.) Anyway, Marshall sure torched us, and the rest of the league But I don't see VY's behavior changing enough, since I have no idea if he's doing the work it would take, and he would just be extremely "high risk" and a distraction in the Seahawks locker room. Wise decision by PC/JS to discuss him, but NOT actually bring him in. I wouldn't be surprised if the sociopath + PD issues have been observed and catalogued by the rest of the league and found to be so profound that nobody wants to take a chance on him.
