The Green Bay Packers took an early lead over the St. Louis Rams on Sunday when quarterback Aaron Rodgers exploited a blown coverage and found wide receiver Ty Montgomery for a 31-yard touchdown in the first quarter.

Montgomery, a third-round pick in this year's draft, is an emerging star in Green Bay's offense. After scoring his first NFL touchdown against the Chiefs in Week 3, the rookie receiver enjoyed his second career Lambeau Leap on Sunday against the Rams.

Rodgers' remarkable start to the season continues with his first-quarter touchdown toss. Montgomery's score was Rodgers' 12th of the year, and he still hasn't thrown an interception. That is a still-growing personal record for the Packers passer, according to Ryan Wood of Press-Gazette Media.

Rodgers and the rest of the Packers' high-octane offense are showing no signs of slowing down in Week 5.
