If the NFL draft is time for optimism for fans of every team, camps are when teams have their rays of sunshine.
It's the same every year. Around the league, someone from almost every team will talk about how the Super Bowl is the goal of the season, how someone is looking way better than last year or how this team just feels different.
Everyone is 0-0 and has his sights on winning 16 of the next 16 games en route to a playoff berth, spot in history and probably a bust in Canton, just for good measure. This optimism is what fuels players through the slog of workouts in the hot sun (or in the reasonable climate of a practice bubble).
If one takes a step back from all the positive spin, it's clear that some teams have big questions to answer before the season begins. It doesn't change the fact that some of these teams could still have great seasons, but they're not ready for the season to begin...yet.
