Jerry bought his way into a position of power. Just because Jerry owns up to some of the dumb moves he has made as General Manager, does not make it any more palatable.
I was listening to an interview with Parcells on the radio today and he was asked what he thought of Jerry Jones (among other things). Basically Parcells said he had a very positive experience working with Jerry, and that Jerry was very passionate about winning. He also said that the biggest problem with Jerry, was that he listened to too many outside sources. This would be OK if he was talking to somebody that actually knew what they were talking about, but could be a big problem if the person that Jerry was "listening" to wasn't that knowledgable (sound familiar?).
Jerry is a jack of all trades, but master of none when it comes to being a GM...just my 2 cents. We need a full time GM and capologist to truly be competitive in todays NFL.
As a long time Cowboy fan I think we are doomed to mediocrity unless things change at the top.
