I think it's a great pick - I know people are frustrated with another CB, but in terms of diversifying the sort of talent and skill set we have at the position, Dowling is unlike the other players we have.
For years, people have been complaining about the kind of cb's BB drafts - quick-twitch smurfs. This guy is big, physical, and fast. He's played solely on the perimeter but as BB said in his press conference, he's got the skill-set for safety.
Dowling gives us a chance to really change up our back 7 looks. In a nickel look, we can have McCourty and Dowling on the perimeter, and put Bodden on the slot.
Those 3-safety looks that BB loves experimenting with? Now we can put chung (with another year's experience) in the box to decapitate people, maybe give Meriweather the ability to put those ball-hawking skills to use. He's not a pass-rusher, but if BB sees a free agent he wants to sign or he's comfortable with Cunningham's progression, Dowling gives us some pretty interesting options with what we can do coverage-wise
