Harbs has put himself in the role of absolute team leader, jettisoning contentious veteran leaders like Boldin, Pollard, etc. Problem is, it takes peer leadership to reinforce the discipline, habits and focus necessary to be a pro. Committing to proper technique, focusing on the scheme/plays (hello, secondary), and avoiding penalties are all about execution. Since Harbs has elevated himself, he's probably struggling to find enforcers in the locker room. Biscotti will take notice, no doubt.
