Glennon, who joined the Bears believing he had a legitimate chance to become the team’s franchise quarterback, immediately knew his days were numbered when Chicago made Mitchell Trubisky the draft’s No. 2 overall pick just six weeks after his signing.

The end came after four pedestrian games in which Glennon had committed eight turnovers and gotten sacked eight times while leading an offense that averaged a paltry 15.3 points. Like in Tampa Bay the previous two seasons with Jameis Winston, Glennon spent the rest of the season on the sideline watching a neophyte QB (Trubisky) take his lumps.

Cousins should offer a much higher floor, given that he’s been playing at this level for nearly three full seasons since the famous “You Like That?!” game against the Buccaneers.

He has played with a solid offensive line in Washington and had useful receivers from Jamison Crowder to Chris Thompson alongside him, but the running game was a mess most of the time under Jay Gruden, ranking 32nd in DVOA in 2015 and 28th last season.

(To be fair, they were fourth in 2016.) Just as Keenum got a boost from playing in Minnesota, it would hardly be a surprise to see Cousins reach new heights, too.

The coaching infrastructure should be sound, given that Minnesota blocked quarterbacks coach Kevin Stefanski from leaving and replaced Pat Shurmur with highly regarded Philadelphia quarterbacks coach John DeFilippo.

In that limited time of regular-season play, he completed 64.7 percent of his passes with six touchdowns and two interceptions. His career 93.6 passer rating would’ve landed 13th among the numbers put up by starting quarterbacks in 2017 ahead of players like Ben Roethlisberger, Matt Ryan, Dak Prescott, and Derek Carr.

A fifth-round pick in 2014, McCarron entered the NFL after leading the Alabama Crimson Tide to back-to-back BCS National Championship victories. Since then, he’s had four years of learning from Bengals coaches Hue Jackson, Ken Zampese, and Bill Lazor.

In his brief time on the field, McCarron has been relatively efficient and mistake free. With Kirk Cousins drawing the major attention in free agency, a team may be drawn to the idea that McCarron’s best is still ahead of him and he could quickly outplay his price tag.ravens_172
