Every NFL player can benefit from a full offseason. But last season, there were many players who did not get one.
The lockout presented many difficulties for particular players and even coaches in the 2011 season. For instance, new coaches had little time to take a look at their team and find ways of improving it. Rather than being able to use their offseason to develop their team, these new coaches had to work with what they had during the actual season.
Likewise, the players also had a lot of difficulties—especially rookies and veteran players playing for a new team. These players had very little time getting to workout and practice with their coaches and teammates. As a result, some of them had trouble getting comfortable in their new surroundings.
However, there were also some players that did perform well, despite the lack of an offseason. After having a successful 2011 season, these players are going to have a full offseason to practice with their coaches and teammates.
Whatever these players did last season, there's reason to believe they'll be even better next season.
