McCown was the guy behind Drew Brees that gave stability to that position if the time ever came. In 2015, the time came. McCown performed exceptionally by throwing 31-38 for 310 yards and a QB rating of 89.7. McCown did play for five different teams in his career which included: The New Orleans Saints, Atlanta Falcons, Jacksonville Jaguars, Tampa Bay, and Cleveland.
At 35 years old, the Saints obviously are looking to move into a new era without him. The fact is, this was a business decision. McCown proved that he can play when called upon.
