I do agree that Jerry is the best owner in sports. He almost always puts the performance of the team above his own profit. And while he may not literally coach, he does nudge/influence.
We saw it earlier this year when he opined in a press article that Felix needed to get the ball more. He did. Henson starting over Vinny on Thanksgiving, 2004, is but another example.
So while Jerry doesn't try to 'coach', he definitely meddles. I have no complaints lately as all the meddling seems to help these days.
I hope the team is as fired up as Jerry is. Until and unless the Giants lose, we are effectively in the playoffs now.
