Really, look at all the players in the draft that year and count how many showed some good production. Even the Seahawks don't have any picks from that draft left on their roster, and they won the Super Bowl that year.
Why not compare it to all 32 teams in the NFL and see how that ranking stacks up. I don't have the time or desire to do that. All I know is that if you whiff big on your first two draft picks and at least one of them is a first rounder, then you didn't have a great draft. I think Juice was a reach at 4th round. We lucked out with Wagner and we didn't keep Simon. KLM, Mellette, and Anthony never did much of anything for this team. So essentially 3 players panned out for the Ravens. One is a starting DT that is one dimensional. A very good piece no doubt. The other was a starting RT that while healthy did a good job. The last one is a starting FB and like I said, a lot of teams wait to get these guys as UDFA's. Juice was a nice player, but does he really qualify as a player you drool over? So they had a 33% success rate in the draft. 3/9 players they kept and contributed.
