I grew up in Dallas during the early 90s, so naturally I was a big Cowboys fan. Everybody says as long as Jerry meddles with the team and tries to be the coach, they'll never win anything ever again. The only reason they had success under Jimmy was Jerry decided to STFU for a few seasons, but eventually he couldn't stand not getting all the attention and started up his BS.
And I agree about Gruden. If he screws that up then that's an epic fail.
