I doubt he'll end up in Dallas because Jason Garrett may turn out to be a decent coach, plus I doubt Fisher will want to get into another situation with a meddling owner like he just left. In fact Jerry Jones is probably even worse than Bud Adams.
The Titans have made so many mistakes this offseason it's almost laughable. They got the VY thing right, but then turned around and totally f'ed everything up by letting Fisher get away. He's one of the best coaches in the NFL, and will have work at the drop of a hat next year if he so desires. Also, now they're talking about squandering their draft pick by not taking a QB, which would likely mean a trade for somebody who's not that great like Kolb. I don't understand how they make these decisions, but they seem to get things wrong a lot more than they get them right.
