Offense needs more Talent.
Micah Bernard is an exceptional talent, but I think he would do better as a Safety than a running back. I agree with the link below that he takes on contact instead of using
But Utah's defense has enough talent they are taking a future NFL level safety, and using him at RB to bolster the offensive side of the ball.
Granted this is my take after watching just a couple games, but if Utah had enough Offensive Talent, I think Bernard would have switched to and excelled in an even better defense.
All that being said, I think the team is mentally self destructing which is inhibiting the players from reaching their potential.
