Najee Harris will be the Pittsburgh Steelers’ do-everything back. That’s generally what your plan is when you make the decision to use a first-round pick on a player at that position, and Harris is certainly capable of running the ball, breaking tackles, making catches, picking up blitzes, and doing whatever else might be asked of him.
Head coach Mike Tomlin also has an established history of preferring the ‘bell-cow-back’ model of rushing, whether it was Willie Parker, Rashard Mendenhall, Le’Veon Bell, or, to a lesser extent, James Conner. But offensive coordinator Matt Canada has a greater history of diversity in his personnel usage, at least at the college level, and he did talk about looking at all of the backs available to them for different roles.
