A growing number of professional athletes are using free agency to leave part ways with their longtime teams. Is it a loyalty problem?

This week the NFL has seen many big-name players sign with new teams. It's different from years ago, when most players finished with the teams they spent the majority of their career with.

Is it an issue of players not being loyal to their teams anymore, or is it an issue of teams not doing enough to keep a player around? Wes Welker said in his Denver Bronco press conference that he "wants to win." Perhaps it's just a matter of a player losing faith in an organization.
