Please post a more accurate depth chart if you can, I'm sure I've left people out and have some things wrong.

Anyway, the point is, we have made some upgrades but a lot of work remains. I'd like to see 2 more new starters in the OL, one or 2 more at DL and a couple more linebackers. Pick up 3 or 4 more new starters, slide the incumbents down the chart, and we don't look that bad, especially in the AFC West. I'd say it's realistic to pick up 1 or 2 new starters from the draft. So if we can get 2 more new starters in free agency and from other teams cuts, that would be a really great offseason, filling most of the big holes.

Most of the time, that would be unrealistic to pick up that many new starters, up this team had so many holes, it's not that hard to add that many new starters.
