It seems like the more NFL teams stay the same, the more they change.
The Detroit Lions may fit this description perfectly next season. Most of their offseason has been concerned with bringing their players on board long term, and there have been few, if any, major changes to the team.
No major roster changes, no coaching changes, no quarterback drama, and quite possibly no changes to offensive or defensive schemes.
Or so it would seem, but coaches are always refining their schemes to reflect what does and doesn't work and the talent on the team.
After all, when Gunther Cunningham joined the team in 2009, he talked about blitzing as much as 40 percent of the time. Some three years later, he decided he didn't see the need to blitz hardly at all.
Why the change? He simply altered his scheme to match the talent he had on the team. New circumstances arose, and the Lions adapted.
There may not be a whole bunch of new personnel on the team, but there is a considerable amount of game film showing what didn't work last year. Here are a few tweaks we might see the Lions make to fix that in 2012.
