Their first team LB should be good- Russell and Cooper- and one of their two starting corners should be good in Chappell. Their first team defense, if healthy, should be solid to very good across the board, with the biggest question mark at CB2 (Grimes, McCall, Harmon are all meh). The DL should be very good, and that by itself can keep you in games at times.
On offense, their first team WRs and TE are good. RB seems jaggy, although Moss has some upside. OL is why their first team isn't higher than 10-15th to me, it's a problem with Addazio for strings running the show, even though they have some talent. QB is a wildcard if healthy; I think he's likely erratic with some great moments, but there's a chance he's just really good. Again, this is all assuming good health and only talking first team; Max could transfer and Wiegman could get knocked out week one.
Coaching is included in my estimation. If their first team stays healthy, I think they can play at a 10-15 level if their QB takes a realistic second year step forward.
Of course, they're an injury at starting LB (either), CB (Chappell), and RB (Moss), from having a big drop off
