I think we all accept BB is not perfect and that some decisions aren't going to work out. The thing is he makes a ton of choices, and I can imagine half of them working out and half of them not, but I never know which ones will be which.
You can't possibly predict the future, other than to say not every decision will be correct. Look at the 2011 off-season. We get Haynesworth and Ocho, but neither made an impact. But the last-minute scrub signings of Andre Carter and Mark Anderson turned out to be the great ones.
As far as this discussion, it's always easy to look back in time and cherry-pick results, but if you're going to do so, you might as well look at the entire picture and provide proper context. Sure, Cincinnati did "better" in one decision but they also drafted Jermaine Gresham over Rob Gronkowski. And their best draft pick was actually their 4th rounder, Geno Atkins. So it's clear they lucked into and out of a few things as well.
They had a pretty good draft in 2010, but so did we. 4 starters (5 including punter Mesko), 3 of which have been voted to Pro Bowls in McCourty, Gronk, and Hernandez, is a pretty good haul. If we didn't have the best draft that year, we had to be near the top.
With Pro Bowlers like Bowman, Graham, Hernandez, Atkins, and Chancellor all taken in the 4th round or later, you can pretty much point out every team regretting a few picks from this draft. Look at the second round alone. The Ravens took Kindle before all of them. The 49ers took Taylor Mays. The Packers took Mike Neal. The Giants took Linval Joseph. The Seahawks took Golden Tate. These are all very good organizations with very good track records and they all could have done better with their picks. It's clear now we should have drafted Hernandez before Cunningham or Price too.
I don't mind people looking at specific decisions or mistakes. I'm sure BB looks at them constantly to learn from them as well. But it would be nice if there were some context or insights as to why a pick failed rather than pointing out the obvious, which has been pointed out numerous times before. Sometimes I do think people expect perfection, as if the 2007 regular season blinded us to the reality of the NFL. Yes, we missed on a draft pick. So did everyone else. Multiple times. It will happen again. Don't act so surprised when it does.
