Houston at Chicago on the NFL schedule might give some older fans flashbacks of two of the greatest running backs in the history of the game: Earl Campbell from the Houston Oilers and Walter Payton from the Chicago Bears, legends of the 1970s and 1980s.The two Hall of Fame backs only met head-to-head once; a 10-6 Oilers victory in 1980 in which Campbell rumbled for 206 yards on the ground and Payton piled up 163 all-purpose yards.This Sunday's game between the Houston Texans (4-8) and Chicago Bears (5-7) probably won't play out like that classic showdown between Campbell and Payton. The Texans and Bears have the NFL's two worst rushing offenses in 2020.The Texans rank 32 out of 32 teams with 84.4 rushing yards per game. The Bears are just slightly better, ranking 31st in the league with 86.9 rushing yards per game.Houston's dead-last ranking is an especially bitter pill to swallow because the Texans traded All-Pro wide receiver DeAndre Hopkins in the offseason to the Arizona Cardinals so they could get former All-Pro running back David Johnson -- taking a big risk specifically to improve their run game.Both teams lost last week to division foes. The Texans fell 26-20 to the AFC South's Indianapolis Colts, while the Bears dropped a 34-30 decision to the NFC North's Detroit Lions.Houston Texans at Chicago Bears Betting OddsTexans odds: -1.5 (-110)Bears odds: +1.5 (-110)Spread: The Texans are a -1.5 point road favorite in Sunday's game at Soldier Field in Chicago.Deshaun Watson makes this look way too easy.
