Rookie DB's

I was voting for the pro-bowl and was stunned when I started looking up stats for the DB's. This year's rookie DB's are among the elite nfl players. Even though I have done no research on the matter, I am convinced this year's rookie DB's are the best of all time.

Greats

Earl Thomas-Most Int's and Passes Defensed among ALL Safeties in NFL while accumulating 56 tackles so far.
Devin McCourty-1st in AFC for ints with 5 (all in last 6 games). Has 17 passes defensed and 61 tackles so far.
TJ Ward-1st in AFC for tackles for DB's that have at least one int (he has 2 ints, 80 tackles, 9 passes defnesed, and a forced fumble)
Eric Berry-1st in AFC for tackles for SS's that have at least two ints. Also 1st in AFC for ints for DB's that have at least two sacks. (he has 58 tackles, 2 ints, 2 sacks, and a forced fumble)
Nate Allen-1st in NFL for ints Safeties that have a sack (2nd for DB's). 2nd Most (Behind Earl thomas) for most ints of FS's in NFC. (he has a sack, 10 passes defensed, 3 ints)

Notables
Alterraun Verner- Has started the last 6 games, and in those 6 games has had 2 ints 11 passes defensed and 35 tackles (6 per game)
Joe Haden-13 passes defensed and 3 ints
Cody Grimm-Has started the last 8 games, and in those 8 games has had 51 tackles (6.5 per game), 2 ints, a forced fumble, and a touchdown.
Kareem Jackson-Is the number one corner on his team (granted it is the worst in the NFL for pass defense), and he has 49 tackles, 2 ints, and 10 passes defensed
Morgan Burnett was doing great in the 3.5 games he played before he was put on IR

This was a pretty good draft class as a whole, it seems. Lots of playmakers.

Kareem Jackson is a reason to be wary of stats. From what I heard, the Texans shittiness in defending the pass(and thus being incredibly reliable for opposing QBs in fantasy), is in part due to him.
