Colts vs. Bears Week 4 Vegas spread, betting odds: Mitch Trubisky Era over? Nick Foles will start at QB for Chicago

This bears repeating, and pardon the pun: Chicago Bears general manager Ryan Pace traded up one spot in the 2017 NFL Draft to take North Carolina quarterback Mitchell Trubisky at No. 2 overall. Pace could have stayed put and selected either Patrick Mahomes or Deshaun Watson. It was nothing short of a colossal, franchise-changing mistake and it could be that the Trubisky Era has come to an end in Chicago. The team announced Monday that Nick Foles, who led a huge comeback victory Sunday in Atlanta in relief of Trubisky, would start Week 4 vs. the Colts. Even though the Bears are unbeaten, they are 2.5-point home underdogs on the William Hill NFL odds.

With the Bears down 26-10 in the second half, Nagy pulled Trubisky on Sunday and Foles threw three touchdown passes in the fourth quarter to shock the Falcons 30-26 and put Atlanta coach Dan Quinn on the hottest seat in the NFL. Foles had two additional touchdown passes overturned by the officials. He finished 16 of 29 for 188 yards and three touchdowns with an interception, and that pick was a rather questionable call by the officials.

The Bears became the first team in NFL history to win two games in a single season where they were trailing by at least 16 points entering the fourth quarter. They also did it Week 1 in Detroit thanks to three fourth-quarter TD passes from Trubisky.

The Bears are 3-0 for the first time since 2013 and finished with an unbeaten September for the first time since 2010 -- the last time they reached the NFC Championship Game. Sunday will be Foles' first game at Soldier Field since beating the Bears in the playoffs while quarterback of the Eagles in a Wild-Card game following the 2018 season (the double-doink Cody Parkey game).

Nagy had announced Sept. 6 that Trubisky won the starting job over Foles in training camp in a bit of a surprise. In regular-season games in which he has thrown at least one pass, Foles is 31-25 straight up and 25-29-2 against the spread. He was 0-4 SU and ATS last year with the Jaguars.

The news isn't all good for the Bears as they fear that pass-catching running back Tarik Cohen tore his ACL in the Falcons' win. He was injured on a punt return. Cohen had just recently signed a three-year extension.
