For much of the 72-plus minutes of football at Ford Field Sunday, the Lions looked like they might find yet another strange way to lose this season.

Instead, the two faces of their franchise — wide receiver Calvin Johnson and quarterback Matthew Stafford — made the biggest plays in the biggest moments to help the Lions (1-5) earn their first win of the season and end any speculation that 2015 could spiral into another winless season.

After a 57-yard pass from Stafford to Johnson, Lions kicker Matt Prater made a 27-yard field goal to give them a 37-34 win over the Chicago Bears (2-4) with 2 minutes, 29 seconds remaining in overtime of a game in which both teams — and possibly the officials — made several errors.

Stafford also threw a 6-yard touchdown pass to Johnson with 21 seconds left to cap what appeared to be a fourth-quarter comeback on a day in which the Lions' offense finally made good on its potential, testing a suspect Bears secondary deep and creating eight passes of 20-plus yards.

"Heck yeah," Johnson said when asked if the aggressive passing attack felt more comfortable for him. "We're getting a win and making big plays. No doubt about it."

Johnson finished with six catches for 166 yards, including receptions of 57, 43 and 39 yards that were his three longest of the season. It was his best yardage output since Week 11 of 2013.

Stafford was 27 of 42 for 405 yards — his most yardage since throwing for 488 in Week 8 of 2013 — with four touchdowns and the one pick. He had a critical intentional grounding penalty on the touchdown drive late in the fourth quarter, but an unnecessary roughness call on Bears linebacker Pernell McPhee, who hit Stafford low and late on the next play, minimized the damage Stafford's penalty.
