The answer is, yes.
There were critical years in 1981, 1987, 1988, 1992, 1996, 1997, 2003, 2004, 2005, 2006, 2007, 2008 and 2009. This list identifies the years when the Oakland Raiders lost more games than they won, from 1967 to 2009.
Looking at the earlier years we see the following in wins, losses, and ties:
Year Wins Losses Ties Ratio
1966 AFL Oakland Raiders 8 5 1 8/5 1965 AFL Oakland Raiders 8 5 1 8/5 1964 AFL Oakland Raiders 5 7 2 5/7 1963 AFL Oakland Raiders 10 4 0 10/4 1962 AFL Oakland Raiders 1 13 0 1/13 1961 AFL Oakland Raiders 2 12 0 2/12 1960 AFL Oakland Raiders 6 8 0 6/8 My method of analysis labels a year "critical" when the losses exceed the wins. Hence, we have several critical years:
1960
1961
1962
1964
Note that in 1967, the Oakland Raiders reached a maximum win-loss ratio of 13, with 13 wins and one loss. Here is a portion of the data for 1967

Another interesting observation is the record of the three consecutive years with the highest win-loss ratios. The three years are 1967, 1968 and 1969. There is no other three-year period with high ratios in the dataset.
According to the historical archives, we have:
