Sure its not all his fault but you can bet if he wanted to keep more of the stars he has lost they would still be in Pitt.
Since he started coaching they've lost some of the better(not necessarily greatest but better) Steelers of all time
awson, the Steelers second incredible center.
Rod Woodson-HOF no doubt
Carnell Lake-loved that guy
Barry Foster-excellent back for a brief time

Yancey Thigpen(1300 yard WR) gone because they don't pay him big $. There other WRs at the time were
Neil O'Donnell, Jets pay him big $
Eric Green(like it or not) is still one of the most talented TEs they've ever had
Greg Lloyd, geesh was he a beast. He was on his way to the HOF
Kendrell Bell, KC
Hardy Nickerson(I'd consider voting for him for HOF if I had a vote)
Kirkland was a giant at LBer
IIRC Kevin Green or Gildon are 1st and 2nd in sacks in that team's awesome defensive history. Both gone.
Didn't Searcy go to Baltimore?not sure
I probably named a small small portion too.
There isn't a coach in the NFL as resillient as Cowher. IMO you should be "on" the front office for that and be thrilled ya still got him. I'd figure most coaches would leave if they watched that many great players walk.
