In just the last three NFL seasons the Bears have changed every significant skill position on the offensive side of the ball. Gone are quarterback Jay Cutler, running back Matt Forte, wide receivers Brandon Marshall and Alshon Jeffery, and tight end Martellus Bennett.

It's a new era in Chicago for more reasons than one, and Monday Morning Quarterback's Peter King shared his thoughts on what that might look like in his latest NFL Power Rankings.

King has the Bears ranked 28th, ahead of just the New York Jets, Cleveland Browns and San Francisco 49ers. But he's optomistic on a few fronts.

  • Free-agent signing Mike Glennon is grinding his teeth over the drafting of QB Mitchell Trubisky (second pick in the draft), and he has one season to stake his claim for the job. (I wouldn’t be optimistic in the Glennon household.)
  • Second-round tight end Adam Shaheen will step in early in a prominent offensive role.
  • The starting quarterbacks from 2016—Jay Cutler and Brian Hoyer and Matt Barkley—were all let go, an odd development for a team that retains the same coach, offensive coordinator and GM
  • At quarterback, I don’t just assume that Glennon/Trubisky will automatically be better than what Chicago had last year. Thankfully, running back Jordan Howard came out of nowhere (the 2015 fifth round) to gain 1,313 yards, to rank a stunning second in the NFL. It’s vital he doesn’t have a sophomore slump. In short, I can’t see the Bears being .500 unless one of the quarterbacks emerges as a top 20 passer by early in the season.
  • Most important factor to this team this year: Of course it’s the quarterback race between Glennon and Trubisky. That one’s too obvious. There’s another one. Kevin White was the seventh pick of the 2015 draft. In two years, he’s played four of 32 games, caught zero touchdown passes, and had zero impact. This is the year the Bears have to see some degree of explosiveness and/or competence out of a player drafted ahead of Vic Beasley, Melvin Gordon and Marcus Peters.
  • Bears prediction of 10 words or less: Trubisky is the quarterback by Thanksgiving. It doesn’t matter.

King's final thought might be his most interesting. Trubisky starting by Thanksgiving would put the Bears in Week 12. Quarterbacks coach Dave Ragone doesn't seem intent on delegating any starting duties out in the preseason, but perhaps that would change as the season moves along. Shaheen will be asked to do plenty of learning and growing in his first season, while it's clear White needs a breakout season after the Bears moved on from Jeffery in the offseason.
