Okay, DeAngelo Hall is consistently in the top 10 in terms of intereceptions every year. He has six career non-offensive TDs, so he's averaging just under one per season. The defense of Hall as a player begins and ends with the fact that he scores a few points for you every season.

Point is, when you expand the definition of playmaking CB to include results outside of INTs, I just don't think he stacks up to some other elite players at his position. It's my opinion that "getting interceptions" is too rare of an event to completely define a playmaker in the secondary. Big hits matter. Stripping the ball matters. Difficult pass breakups matter. Run defense matters. Some will disagree. I think a true playmaker does most of these things.
