NFL Free Agency

Today, Wednesday March, 9 is the beginning of the NFL and the free agency for the 2016-2017 NFL season.  It is amazing how so many players jump ship to another team for a higher pay check and leave behind the team they were with.  Of course there is other factors that play a roll, but a lot of the time it is for the salary they will be playing for.  Days like this is a holiday for football fanatics as the league is mixed up and teams start a run at a Superbowl.  It is hard to put yourself in their shoes, but what are other big factors in leaving a team.  Is it the relationship with the front office, or maybe the city they play for?  I feel there are a lot more factors than just money in why people leave, but it is pretty amazing to me the power money can have in forcing a player to jump ship.
