This post is riddled with fail.
"Matter of fact, very few Iowa DBs make it as DBs in the NFL"
Sean Considine
Derek Pagel
Bob Sanders
Bradley Fletcher
Marcus Paschall
Tyler Sash
Amari Spievey
Micah Hyde
Shaun Prater
Charles Godfrey
and Matt Bowen all say hello.
How many Iowa DB grads made it, at least, 3 years as DBs in the NFL??
Sean Considine a safety at Iowa played mostly on special teams in the NFL... I remember him with Philadelphia, mostly.
Derek Pagel? where did he play and for how long as DB?
Bob Sanders was a special player. He was known for his hitting more than his DB defense. Played as safety at Iowa and NFL - could have been considered another linebacker for the Colts (which was how he was used at Iowa). Is that player development?
Bradley Fletcher, a CB at Iowa who started out at STL and now plays for Philadelphia as a CB (had to Google). How long has he played in the NFL?
Marcus Paschall? I remember the name but don't remember his NFL DB exploits... why don't you enlighten me?
Tyler Sash.. safety at Iowa who is a special teams player in the NFL. Mostly with the Giants.
Amari Spievey.. epic fail. I mean, he was an epic fail in the NFL. Played cornerback at Iowa. Drafted number 1 by the Lions to play cornerback and by his second season was switched to safety, and after 3 years the Lions didn't want him, heck the league didn't want him.
Micah Hyde... Played as safety and cornerback at Iowa. Has played one year at safety for the Packers. He's a good athlete, but doesn't prove anything about player development at Iowa (or Green Bay).
Shaun Prater a DB for Iowa playing as a DB for I want to say Philadelphia now? Been in the NFL for 3 seasons.
Charles Godfrey a DB for Iowa playing as a DB for Carolina. At least 3 seasons in the NFL.
Matt Bowen? What did he do? Special teams at, I want to say Green Bay?
Of those 11 players you listed, as far as I can remember:
4 of those you mentioned either didn't play at their position in the NFL as Iowa (I count Spievey)
3 of those you mentioned I don't remember. I wonder what kind of NFL careers they had.
1 Sanders had a great career at the Colts with about 8 seasons in the league (talk about a concussion statistic)
3 played DB at Iowa and play DB currently with the NFL with at most 3 years in the NFL.
One can look at this another way:
This isn't scientific, but Since 2003 (I'll use 2003 as the first year of Iowa's 'greatness' under KF and the defense):
There have been 11 Iowa seasons since 2003.
That means 22 different cornerbacks and 22 different safeties could've played for Iowa since the 2003 season.
Divide those numbers by 2 (I assume each player played for 2 seasons at Iowa) and you get
Approximately 22 different CBs and safeties have played for Iowa since 2003.
Of those 22 supposed different Iowa DBs since the 2003 season:
4 I come up using your list of Iowa DBs that stayed at their positions for, at least, 3 years in the NFL.
3 I don't remember their NFL careers.
1 is an unknown - Hyde.
Not so sure your list proves any kind of superiority of Iowa DB development.
