For all the Harris haters? I took the article as basically say, "Harris is more an athlete than a RB, and he really needs to work on his footwork is he wants a future in the NFL."
Some notes include:
"Although he has improved his all-around game, he is still not a high-level NFL starter with refined skills between the tackles."
And the writer ultimately concludes:
"Right now? He’s potentially an NFL athlete who will excite evaluators who don’t understand nuances the position and hope Harris will magically figure it."
That's not exactly an endorsement.
