A lot of teams are just a 'top notch' QB short from competing or morphing into contenders, the problem being that these type of players aren't widely available, so I think with the new and young O-Line combined with the emergence of the receiving core, pulling the plug on Romo is too premature imo, although I do agree they should have a backup plan, or someone to groom for the next few years, but that's not simple either for the same reasons above.
