I don't think it's comfort as much as it is the caliber of player.
This is really the first time Pearl has had kids who are expected to be the elite by the public. Prior to TN, Pearl had athletes who were either by-passed by the top tier schools or were a slight step down from the elite players in natural ability. When he first came to TN, our program had sank so low that we had similar players here as what Pearl was used to coaching. These types of players have a tendacy to "want" to play as a team to prove a point. (Rather the point be that the big schools shouldn't have passed on me, or rather it be I'm good enough to play with the top athletes.)
Now, Pearl has built back our reputation so that he has top tier rated athletes, and these kids have been told since they started playing sports that they are the "best." It takes a different caoching ability to coach up a player who knows he is in "the best" category. I think Pearl will get them going, but I also think this is something a little new for Pearl.
