I'm really coming around to the idea that our losses have been due to the lack of offensive and defensive game planning. I don't think we overrated our talent (although there is room for improvement at certain positions) but I do believe we are behind the curve with our strats on both sides of the ball. Other teams are doing more with less as a result of scheme. As someone stated in another thread our strats require our players to be a superior player with the "beat the guy in front of you" mentality l which is not realistic in today's NFL. Today's NFL requires more strategic planning and gimmicks to succeed. It makes sense because card games such as Magic the gathering and hearthstone are similar to the NFL because it's a copy cat kind of game such as the NFL. The teams that are good (as well as decks used for the above card games) succeed because they are not doing what everyone else does and tries to innovate to be ahead of everyone else.
tl;dr
We lose due to lack of game planning and the plays we run plan on both sides of the ball. Not talent.
