It is a training facility for coaches, but also an opportunity for fans to watch a coach on the sideline.
Cornerstone Training is a four-year program designed to bring together NFL players and coaches to work on the same basic goals.
It is designed for players to develop and improve their skills in order to prepare for the NFL and develop a better understanding of how to improve as a person.
The program also serves as a place for players and teams to share information and to connect.
For the coaches, it is a chance to work with a variety of coaches and players.
They will work on everything from the fundamentals of coaching to developing an approach that is more approachable.
The programs are hosted by the Dallas Cowboys and the Kansas City Chiefs.
The training facility was opened in 2010 and opened in the fall of 2011.
The Cowboys are in a rebuilding mode after their franchise-record-tying nine-year playoff run ended last season.
The Chiefs are rebuilding after their disappointing 2015 season.
They had one of the worst rookie classes in the NFL.
The first day of training camp was the first for players since their new team is a new one, and they will try to build on that experience and the progress that has been made.
The team also plans to open the program in October.
The Dallas Cowboys have been a frequent visitor to the Cornerstones Training Center.
Here are some of their visits.

The Raiders are taking a visit from the NFL on Wednesday.
They began training at the facility last year, and the team plans to continue to work in-person on Friday.
