Prior to 2008, Hurney traded for or signed the following veteran players:
Mark Fields, Stephen Davis, Ken Lucas, Mike Wahle, Justin Hartwig, Chris Harris, Keyshawn Johnson, Na'il Diggs, Ma'ake Kemoeatu
I'm not counting the fringe players who made good, like Jake Delhomme, or Damione Lewis. All of those players had extensive starting experience, and were well known free agents that other people wanted. And not all of them worked out. But the point is, he went out and got solid veterans.
And then he suddenly stopped. After 2009, he's signed/traded for:
Greg Olsen, Jeremey Shockey, Mike Tolbert
Fox got no one in his last two years, and had his entire roster all but purged of veterans. That's also not characteristic of Hurney, but it's pretty much accepted that he did it because Richardson told him to. And then there's the whole Peppers thing, where Hurney never tried to trade him away, even after it was apparent that he wanted to go. Through it all, he did a great job at cap management, for what that's worth, but it;s almost like he was a completely different GM after Richardson got involved again and fired his kids.
The fact that he stopped was because if he didn't he was going to be out of a job just like Fox for his poor performance. JR set goals that Fox nor Hurney met and that's why both got fired. Not because of some half baked scheme.
