Aside from WDR (obviously), as best I can tell the consensus among fans is that the Bengals off season was solid.
In fact, people would likely rank it better than most other teams had. Given that those other teams have real front offices not run by a small clique of friends and family like the Bengals, I think people might wonder, "So why do we need to oust control from the Brown Family anyway?"
Well the main reason is 18 years of history. But let's focus on something else since overwhelming historical evidence is apparently unconvincing.
I read this article the other month by Bill Simmons, who I conservatively estimate drives 2/3rds of all web traffic at ESPN.com. In it he discusses how the NBA front offices are trying to use new statistics to better capture how productive players are; in other words, they are trying to do for basketball what sabermetrics did for baseball. Just like wins, batting average, RBIs, etc didn't capture as accurately as possible player performance in baseball...traditional points, rebounds, assists, etc. just do not capture as accurately as possible player performance in basketball.
The GM of Houston, Daryl Morey, receives special attention in the article because of his particular tenacious focus on measuring better stats, like quantifying the impact of a role player:
After watching Anderson Varejao throttle the Clips with his low-post D recently, I e-mailed Daryl, wondering why there wasn't a stat called Stops, for when a defender prevents his opponent from scoring on an isolation play, or a low-post or perimeter play. Come up with an unforced turnover in the process, and it's a "Superstop." Daryl's response: "Why do you think we have Chuck Hayes?"
And of real importance was this line:
The statistical intelligence in NBA front offices is superior for one simple reason: They spend millions of dollars to figure this stuff out. Daryl has many minions crunching numbers. At the conference, Hollinger joked that Daryl was lucky the league hasn't imposed a salary cap on stat guys.
Measuring more nuanced stats is easiest in baseball since you really only measure one isolated event at a time (each at bat). Basketball is more difficult as you have a fluid, continuous state of play with ten players simultaneously affecting the outcome at all times. Football adds even more complexity. But just because it's more difficult does not mean progress cannot be made and isn't already being made.
