Rebuilding the OL through the draft is the only way to go. You can find quick/superstar development lineman in all rounds of the draft, and get their run blocking up to 90+ within 2-3 seasons, then focus on awareness and other blocking attributes. I don't really care about pass block ratings because I user the QB anyways and my custom playbook is full of quick passes.

Having a star HB is also key. You don't need a 90+ overall halfback, but traits matter a ton with breaking tackles and establishing a productive run game. I personally draft somebody with 90+ speed, upgrade all the traits, then focus on carrying and ball carrier move attributes then awareness/ball carrier vision last just to boost overall rating.

I personally don't bother too much with WR/TE positions, because I hardly notice a difference in ratings, besides having a "star" receiver with all of the catching traits and 90+ attributes that you can just throw the ball up to when you're desperate, but that type of player isn't needed. Same thing for TE. I don't really know if it's coverage mechanics or run routing animations, but pass defense is just terrible this year. You can have a 74 speed 65 route running blocking TE get 5 yards separation on an out route against elite safeties and corners.

On the DL, I actually prefer linemen with low block shedding attributes, because I want my linebackers to get more tackles for statistics purposes. I run 4-3 and typically fill the line with fast agile pass rushers.

For the LB, I like fast backers with 80+ zone coverage and block shedding/pursuit.

For DB, it doesn't really matter, because as I said either pass coverage or run route animations just ruins everything, regardless of how good or bad your secondary is. The best thing I do for these positions is upgrade traits to get more interceptions, but I've really seen no difference since year 1 of my Saints CFM to my season now with 85+ overall safeties, a 89 CB1, 83 CB2, and 81 CB3, all with 80+ zone coverage and play recognition.
