There have been a lot of misses.
- Percy Harvin (If you count him)
- Kris Durham
- Amara Darboh
- Kenny Lawler
- John Ursua
- Dee Eskridge
- Kevin Norwood
It's about 50/50.
I wasn't counting trades, but I wouldn't think of Harvin as a miss either. Injury isn't a scouting problem; he was diagnosed with the hip injury months after the trade.
Harvin aside, I would really only count Eskridge and Darboh as misses on your list, since they were in the second and third rounds respectively. You want someone who will contribute to the team in those positions. The fact I didn't even recognize Darboh's name says something to me.
Norwood and Durham were both 4th rounders, where you at least hope you're getting a depth player, but a lot of 4th rounders don't make the team. If you wanted to call those 'misses', I wouldn't argue but wouldn't completely agree either.
I would consider anyone in rounds 5 to 7 who makes the team to be a resounding success. Lawler and Ursua were both 7th rounders. Ursua actually made the team and was eventually let go after a torn ACL. Not great, but not a miss. Lawler made the practice squad, which I wouldn't consider a miss in the 7th round either.
