Couple things: First, you got to learn how to lose before you can learn how to win. Second, it is true, other teams have said you cannot mimic the speed of the Broncos defense in practice. It is much faster in real life. 3rd, the Panthers played all year with big leads, and didn't know how to adjust (new territory) to being behind and not being able to impose their will...... which leads to frustration, which leads to bad decisions, which leads to stupid penalties, which leads to a loss.......
