Personnel executives from the other NFC North teams seemed to think so. (link to Milwaukee Journal Sentinel)  Best O-line and D-line too.

I broke down the numbers from the article.  If you don't read the article, ratings are given as follows: coaches rated the top 3 at each position from 3 (highest) to 1 (lowest).  They were not permitted to rate their own players.  Offense and Defense had 11 starters and 6 backups, and Special Teams had 5 positions that I considered as starters.

Offense

Team: Starting Avg (Points) / With Backups (Points) / #Starters / #Backups

1. Detroit: 6.54 (72) / 6.47 (110) / 5 / 3
2. Green Bay: 6.54 (72) / 6.35 (108) / 5 / 2
3. Chicago: 5.45 (60) / 5.88 (100) / 2 / 3
4. Minnesota: 5.45 (60) / 5.06 (86) / 2 / 0

Defense

Team: Starting Avg (Points) / With Backups (Points) / #Starters / #Backups

1. Green Bay: 7.0 (77) / 6.59 (112) / 5 / 2
2. Chicago 6.09 (67) / 6.47 (110) / 4 / 3
3. Minnesota 5.55 (61) / 5.47 (93) / 1 / 2
4. Detroit 5.36 (59) / 5.47 (93) / 3 / 1

Overall (incl ST)

Team: Total Points / #Starters / #Backups - Rank

1. Chicago: 247 / 8 / 6
2. Green Bay: 240 / 10 / 4
3. Detroit: 232 / 9 / 4
4. Minnesota: 213 / 6 / 2

(Detroit) Stats of note:  Unanimous best at their position: Jeff Backus, Rob Sims, Drew Stanton (QB2), Ndamukong Suh.  Consensus best (* indicates shared): Calvin Johnson*, Gosder Cherilus, Tony Scheffler (TE2)*, Corey Hilliard (utility OL)*, Cliff Avril, Turk McBride (utility DL)*, Stefan Logan (KR)*.   Best O-line: Detroit - 3 Starters, 1 Backup; Best D-line: 2 Starters, 2 Backups.  Stefan Logan rated first as KR and second as PR.  The Detroit back seven was absolutely wretched, with all of our starters, excepting Delmas, rating last at their respective positions.  I think Levy will be more respected once he gets some legit talent around him, but for now, we're in the cellar there.  I do think we're only a linebacker, a cornerback, and a Matthew Stafford away from a playoff game though.

(Other) Stats of note: Best Linebackers: Chicago - 2 Starters, 1 Backup.  Best Secondary: Green Bay - 3 Starters, 2 Backups (wow!).  Best Special Teams: Minnesota - 3 Starters.  3 of Minnesota's 6 starters were on Special Teams.  How did it all go so wrong for the preseason Super Bowl contenders??
