QB

Quality starter and developing backups
WR

Jamo > Chark; as good as ARSB was a year ago, I think he's going to be even better this year
RB

debatable - we'd like to think Monty>Jamaal + Gibbs>Swift but for now I'll say it's a wash
TE

LaPorta could be pretty special Y2 onward, not sure about this year, but the other guys were productive in limited utilization
T

No changes if Nelson is still the swing tackle, & we hope Sewell continues to refine his craft, he's already a top RT
G

Big V seems to be tracking to playing again, potentially good depth with Graham + Sorsdal
C

Ragnow is tough as nails but he'll be in pain all year (inoperable foot injury); Pierschbacher is a downgrade from Evan Brown
K

below average and they don't have a solution
Overall, they should continue to be a very good gap run scheme team. The exceptional (Top 5) OL and Goff-to-ARSB is a stellar baselane. Explosives could come from Jamo, Gibbs, and LaPorta - but those are not proven commodities. Ben Johnson is an elite OC and his play calling gives Detroit a schematic advantage most weeks. Should easily be Top Ten offensively with potential to be Top 5 (their passing attack was 4th in EPA last year.) There are no weaknesses here, except for QB and St Brown they could absorb an injury and not lose much with the next man up. With stars - but no true superstars - the sum is greater than the )(very) talented parts. Fundamentally sound team that doesn't beat itself, takes care of the ball and doesn't make too many penalties. Details are everything for this team.
DT

McNeil has transformed his body (lost 13% of body fat but still 325), Buggs was a good resign, Martin is a project but good physical traits
ED

Hutch should make a leap from good to great, R Okwara and Harris are healthy again, Cominsky can slide between 5-tech, 4I, 3-tech - good rotation
iLB

As Coach Shep noted this week, they're not handing the role to Jack Campbell, but ultimately that pick should be a huge upgrade.
OLB

Will be interesting to see the roles for Rodrigo, Barnes and James Houston IV - very different skills. Houston was not very disciplined in his responsibilities but was an elite pass rusher.
CB
Massive upgrades with the Moseley and Sutton signings, and Jerry Jacobs will fight for a starting spot.
NB

CJGJ, Brian Branch & a little Will Harris - raised the floorhere considerably.
S

Will Kerby make a leap in Y2? I think so. Remarkably, Tracy Walker will be fully cleared for TC. CJGJ or Branch might end up here as needed.

Coming off something of a down year by his own lofty standards, Jack Fox is a weapon. Decent passer as well lol.
The offense was great last year; the defense was awful, especially in the first third. After the Miami game they were forced to fundamentally change their defense after 7 g bc they simply did not have the right dudes to play the coverage they wanted. They played a ton of cover zero while going 1-6 - more than anyone in the NFL through week 8 - and rarely thereafter. But I promise you the approach has not changed. They are going right back to what they want to be, bc now they think they have the dudes who can run it. Overall, their pass EPA still ended up 28th. But first half they were historically awful (worst EPA since 2000) and were run of the mill bad the last ten games. They still ended up 15th in calling cover zero - almost all of them the first 7 games - and 2nd in Cover 1. They left their corners on an island a lot. The ended up 8th most in Cover 2, mostly reflecting how they played Weeks 9-18. They rarely play Cover 3 except early downs, hardly ever play quarters or quarter-half (that Fangio b.s. the Vikings butchered so badly last year.) Campbell and AG want an aggressive man coverage D with heavy blitzes on 3rd and long. This team will never at its core be a "let's keep everything in front of us" bend but don't break defense. They don't run many stunts bc they are almost always bringing 5 or 6 rushers. They are going to play a defense that reflects the character of their team - line up, man on man, bring pressure, let's see if you can beat us bc we don't think you can.
There are no holes on this defense IMO. This team will be so much better with the upgrades they made to the secondary. There's a lot of moving parts and a lot of things are in flux - will Pachal stay healthy, can Onwuzurike ever get on the field, will the young stars keep developing - but I'm really excited about what they will be doing on the defensive side this year. We are not thin at any position group, if (when injuries hit I think they have good depth.
Do we have any weak positional group this year? I really don't see one.
Our weakest is probably LB, but that is an improving unit.
IMO, no - but as always, it depends partly on keeping guys healthy. Injuries are always a factor, we probably could not afford to lose any key defenders LT. But 2-3 game injuries that require a next man up, we should be fine. They're going to bring pressure, they're going to be a vocal, loud and obnoxious defense, and it's going to be really fun to watch when they get on a roll. And bc they will be playing very aggressively and it's impossible to always win those matchups, they'll have some spectacular failures. But I think more than we ever saw in Y1/Y2, the defense will become a huge part of their identity.
IMO they probably have to win 12 games to secure a home playoff game. That's a huge ask, especially for a franchise which has exactly six double digit win seasons since 1962. But they have all the right pieces, the leadership, the talent - it's a matter of execution.
