You sure you want to do this?
Please, God, no. Let's not get into this.
I personally think the following should be not too controversial to most (dangerous words, I know):
1. The draft is essentially a crapshoot, as Ravens' Assistant GM Eric DeCosta has openly admitted. With that said, there are clearly some teams that do a consistently worse job than others, despite (as a result) repeatedly drafting from a favorable position.
2. Over the 15 year tenure of BB, the Pats have generally been one of the better drafting teams in the NFL, especially factoring in that they have been drafting from the back of the pack. Some of this may result from system-specific scouting and using their own independent evaluations instead of those of the national services. Having a smaller draft room and a more restricted draft board may also have facilitated draft-day maneuvering.
3. Even the best drafting teams have frequent misses, and go through "down years".
4. With that said, the Pats had a prolonged stretch from 2006-2009 where they drafted very poorly (especially on defense) in comparison with their track record before and after, and missed numerous opportunities. Given the aging of the defense that was apparent from after 2004, this probably slowed re-loading the defense, and may have cost the team some title opportunities. The Moss and Welker trades and the Vollmer and Edelman picks resulted in a somewhat better record on offense during that period.
5. No one is probably more aware of this than BB.
6. No one outside of the Pats' FO knows all the factors influencing those choices, and certainly no one on this board has the knowledge or skills to be anything other than an armchair critic.
7. Since 2010, and particularly since 2012, the Pats seem to be making up for lost time, with a number of very successful picks.
