The Packers' biggest challenger in the division a year ago should slip a bit in 2015, as personnel losses will hurt the defense and Matthew Stafford is being pushed into becoming something he is not.
If you don't look too closely it appears as though the Lions had a dynamite 2014. They just missed out on a division crown when they lost to the Packers on the final day of the season, but they still finished a very strong 11-5 behind one of the league's best defenses and a talented offense that finally added a strong second fiddle to the all-worldness of Megatron.
