The Bears haven't won their first two games of the season in seven years. They were lucky to get past the Lions opening week rallying from a 23-6 deficit. The Bears launched their comeback after the Lions' top three cornerbacks all went out of the game with injuries. 
I remain unimpressed with Mitchell Trubisky. He only plays well against the Lions and he stunk for three quarters.
The Giants' defense has improved especially in the defensive line.  
The Lions bashed the Bears for 151 yards rushing. So Saquon Barkley should be in for a big game. The Bears are missing run-stuffing nose tackle Eddie Goldman, who opted out of the season, and their best pass rushers (Khalil Mack and Robert Quinn) are both banged-up. Daniel Jones set a rookie record with 18 touchdowns on the road last season. The Giants are expected to get back Golden Tate, too. 
The Giants have been excellent as road 'dogs covering 10 of the last 12 times in that role. The Bears have been one of the poorer point spread teams going 3-10 ATS in their last 13 games.
