Three of nine of course is not a good rate. GRob busting is a big part of how that thing ends up looking too, as if they'd hit on that pick it would have been just about right in terms of what to expect given league miss rates per round and whatnot.
3 of 9 is about average. One was a 5th rounder which has a VERY low hit rate, even making a roster is pretty good for a 5th rounder.
Bailey was a solid guy even with jackshit at QB, but tragically that ended poorly.
Jenkins cannot be counted as a miss, he should be counted as a big time hit. He signed a contract making him one of the highest paid CB's in league history so how can he be anything but a hit. The fact that he wanted to get paid by testing free agency isn't anyone's fault, it's how the new CBA has changed how teams do business. Get used to guys deciding to leave for a big fat check. We would ALL do the same thing.
Stacey had a pretty decent season on a crappy team and got traded. That's not a hit or a miss. He was picked 160 overall in round 5.
So really it's better than 3 out of 9. Not to mention Brockers is an above average player.
As far as the discussion about who "won the trade" it isn't even close. In fact it's a blowout. Griffin started 35 games for Washington. His record was 14-21. He isn't playing for them now and got benched. His NFL resume is shit.
Janoris Jenkins had 4 good to excellent years for the Rams. By himself he would win the trade.
