That's some great research... I always knew CB was a high percentage in the first round just from watching and reading the coverage, but that's even higher than I thought. With the way the NFL has become so pass-oriented, its no surprise.
I'll be very interested in seeing how Williams and Gilmore progress as starters, considering the uncertainty with McGee, Florence and McKelvin over the next season or two. The nickel defense could be quite formidable if Gilmore develops quickly and McKelvin can step it up finally.
