Sam Bradford concluded his first season with Minnesota with three first-half touchdown passes, helping the Vikings to a 38-10 victory over the bumbling Chicago Bears on Sunday.

Bradford went 25 for 33 for 250 yards and one interception, finishing with a 71.6 percent completion rate to set an NFL single-season record. Drew Brees (71.2 for New Orleans) set the league mark in 2011.

Kyle Rudolph caught 11 passes for 117 yards and a score for the Vikings (8-8), who started 5-0 before stumbling out of their bye week and never recovering.

The Bears (3-13) wound up with their fewest wins in a non-strike year since 1973 after turning the ball over five times. Everson Griffen returned one of their three lost fumbles for a touchdown.

Jordan Howard, the lone bright spot, rushed for 135 yards on 23 carries to break Matt Forte’s franchise rookie record and finish with 1,313 yards for the season for Chicago.
