I wonder how many Cowboys fans were saying the same kind of things about Emmitt in 1994 when he averaged just 4.0 yards per carry of in 1996 when he averaged a career low of 3.7. Some of you would have been ready to toss him after that year.
Careers fluctuate. Sometimes a player does hit a wall and is done, but sometimes circumstances lead to them having a bad year in comparison to their other years. If there was ever a year where circumstances played a part in a down year, 2020 would be that year.
