Matthew Stafford is a good quarterback, but he isn’t a miracle worker.

Last year, the Detroit Lions had the NFL’s most anemic rushing attack at just 76.3 yards per game. The year before that, they averaged 81.9 yards per game—30th in the league. The season before that, they sat at 83.4 yards per game—dead last in the NFL.

Despite passing for more than 200 yards in just three of those 12 starts, however, Trubisky showed flashes of his athleticism and arm talent. He showed the ability to anticipate throwing windows. And with Nagy & Co. installing a system that will better cater to Trubisky’s talent, the arrow is pointing up on the former No. 2 overall pick.

During free agency, the Bears added a top target for Trubisky in wide receiver Allen Robinson, who’s a technician in the route tree with the ability to make plays over the top and produce in the red zone. The former Jaguar, who tore an ACL in Week 1 last season, racked up 18 red zone touchdowns from 2015 to 2016. Tight end Trey Burton is the new move guy in Nagy’s offense, a matchup piece who can align in multiple spots. And wide receiver Taylor Gabriel brings some real speed to Chicago with the change-of-direction skills to break down defenses in the open field.

These are major upgrades for Trubisky compared to the lineup he worked with last season, and Nagy’s offense — a modern twist on the West Coast passing game — should jump-start Trubisky’s development. Just look at Jared Goff and the Rams hiring Sean McVay as a potential blueprint.

Perhaps the change of scenery will help Kizer, who threw twice as many interceptions as touchdowns and led the NFL with 22 picks as a rookie. Regardless, if he takes the field in Titletown, Green Bay is toast.

The Packers shelled out big bucks in free agency for tight end Jimmy Graham and defensive end Muhammad Wilkerson, a departure from how former general manager Ted Thompson often operated. That smacks of a team that believes it can make a run at the big one this year.

Green Bay can…so long as it has Captain Commercial under center.

With the initial flurry of free agency in the rearview mirror, we asked coaches, execs and insiders around the league to offer their unvarnished opinions on how other teams did — for better or worse.patriots_091
