Things can change pretty quickly in the NFL and these two teams are examples of that.
One of the best parts of the NFL product is the parity that exists in the league. There is constant change in the win totals for each team year to year, making each season totally unpredictable. Look no further than last season for evidence of dramatic changes in win totals. There were six teams that increased their previous number of wins by four or more (Jets, Raiders, Redskins, Vikings, Panthers, Bucs) and five teams who had their win total decrease by four games or more (Ravens, Browns, Chargers, Cowboys, and Lions).
