Nichols showed real burst in the preseason, averaging better than four yards a carry on his way to 87 yards and a score, which is why Pittsburgh keeps bringing him back even after cutting him. He's buried behind co-starters Jaylen Warren and Rico Dowdle, but his practice-squad elevation the moment Dowdle got nicked shows the coaching staff trusts him as next man up.
Strengths: Strong preseason showing at 4.4 yards per carry gives him a legitimate case as Pittsburgh's next-man-up running back.
Weaknesses: Was cut outright in final roster cuts and remains on the practice squad bubble behind two established starters.
