The New York Giants' decision to let running back Saquon Barkley leave in free agency and join the Philadelphia Eagles has been a significant topic, particularly highlighted in HBO's 'Hard Knocks'. Giants GM Joe Schoen and owner John Mara deliberated on the franchise tag and ultimately decided against it due to potential trade difficulties and the desire not to disrespect Barkley with a low offer. Barkley's departure was influenced by the hefty contract of quarterback Daniel Jones, whose performance has been underwhelming since signing a $160 million deal. Schoen emphasized the need to invest in the offensive line to support Jones, indicating that the team's priority was to see if Jones could be their long-term solution. Despite Mara's wish to retain Barkley, the decision was made to let him test the market, leading to his signing a three-year, $37.5 million deal with the Eagles.
