It's kind of hard to say. I'm leaning towards Gilmore because he is playing in a much more difficult era for CBs. In addition, I've seen a few comments talking about INTs. I don't necessarily agree since CBs these days also don't get a lot of INTs to begin with. Look at the best CBs from this era. Guys like Sherman, Revis, Talib all have less than 40 INTs (Talib is leading all active CBs with 35 INTs). Gilmore has 19, so he is on pace to reach somewhere in between Talib and Revis. I'm not really sure why INTs have been decreasing these years but I don't think a lack of INTs should dock any points from Gilmore.
