Look. This is the off season. Lot's of gibberish is said. I wouldn't be surprised if AI wrote the piece. Lot's of stuff is overblown and exaggerated and misconstrued.
The Team Captains are the actual team leaders. Period. All others are simply force of personality...including the wannabees....yes, including narcissists.
And, true leaders (like HCs) will call players "leaders" but they mean it in an ad hoc way for a purpose....often as an encouragement.
And BTW, just because Akers demands his touches as easily the best RB on the team hardly represents narcissism. It represents perhaps the most common trait among lead RBs. It's their mental make up.
