While some blockbuster trades have paid dividends in the form of Super Bowl rings Zach Gentry Jersey , they have also left some teams with their future mortgaged for a mediocre present. NFL roster building is a delicate balancing act and one-sided trades can tip the scales heavily.Trades have a potential to elevate a team from a playoff contender to Super Bowl champion if they fulfill the needs of the team without giving up too much.
