Scouting? His agent isn't saying that teams think he lacks in the skill dept. His agent pretty much just said it straight out that the, "Poison is out." It might not be just Pierre and Marc he's referring to but he's saying that kind of stuff is hurting.
Not referring to skill; more along the lines of work ethic and in-game determination. Obviously, what goes on in the locker room isn't necessarily their department, but I would have to think that the inner circles of every team's hockey operations group (GMs, scouts, etc) are privy to better information than McGuire; even if he makes himself out to be the most exclusive hockey insider.
