Check out Bleacher ReportWe’re getting down to the nitty and the gritty in the National Football League this time of the year.Next Tuesday, teams must be at or below the salary cap (numerous reports have the number at 123 million). And three days earlier, clubs may begin negotiating with perspective free agents from other organizations.So how do you determine that teams actually have the most to lose? Well, it’s pretty obvious that a number of factors must come into play. And that’s why the teams below, for the most part, are either recent playoff participants or clubs on the rise.In a case of a few teams, there may be a large number of free agents that must be addressed. For others, being too close to the cap with less than a week before March 12 may make it near impossible to bring back their own talent.So here’s a look at the teams that stand to lose the most starting next week. And you will notice a fairly prevailing theme with all of these clubs, one that usually proves to be the difference between a great season and a championship one.It should be noted that all financial and salary cap information for the teams in this piece comes courtesy of www.spotrac.com...http://bleacherreport.com/articles/1550363-predicting-nfl-free-agencys-big-winners-and-losers
