Re: Secret Superstar: Kareem Jackson
It's very true that we can't compare Joseph and Jackson in their respective rookie year; the same way we can't compare McCourty with Jackson.
It's better to compare Joseph and McCourty.
They played in more similar defenses.
The Pats played mostly a cover-two defense while the Bengals mixed it up with the Tampa two.
In these schemes, the CB play mostly zone, and can afford to be more aggressive.
When they are in man, they still have two safeties to back them up (cover two, man-under.)
Don't forget that both of those defenses ranked near the bottom in yardage allowed.
It's hard to imagine rookie CBs playing so well despite the fact that the passing D was "terrible".
Jackson was thrown into the fire, playing more on an island.
