Don't get me wrong from his film from he's freshman year he looked like a good running back. But if Green lives up too he's five star status, Johnson comes back healthy, and Smith makes big strides in development could Isaac become a stud LB kinda like Anthony Barr. Both were highly rated big running backs Barr never panned out as a stud RB but did turn into a first round draft pick on defense. Isaac could become a stud running back at Michigan but 6'3 240lbs is a good size for a pass rushing LB and with value of running backs in the NFL dropping plus the fall RB'S careers are shorter then other positions and the big dollars NFL teams invest in pass rushers a switch to defense could make sense for Isaacs future.
