Coming off of a home win against the Cowboys, the Broncos stayed at home, donned their throwback uniforms, and prepared for a Week 5 AFL Legacy game with the New England Patriots.  This would mark the highly anticipated match-up between Denver head coach Josh McDaniels and New England's head coach Bill Belichick. The Broncos would trail in the first quarter as Patriots quarterback Tom Brady hooked up with wide receiver Wes Welker on an 8-yard touchdown pass, followed by kicker Stephen Gostkowski getting a 53-yard field goal.  Denver would answer in the second quarter as quarterback Kyle Orton connected with wide receiver Brandon Marshall on an 11-yard touchdown pass, but New England would close out the half with Brady's 7-yard touchdown pass to tight end Benjamin Watson. The Broncos would tie the game in the second half as kicker Matt Prater nailed a 24-yard field goal in the third quarter, followed by Orton finding Marshall again on an 11-yard touchdown pass in the fourth quarter.  In overtime, Denver won possession and never relinquished possession as Prater booted the game-winning 41-yard field goal. With the win, the Broncos improved to 5-0 for the first time since the team's Super Bowl run of 1998.
