What’s the risk? Answers given: could take years to find a suitable replacement (which will be the case no matter when they move on from the current QB), don’t you remember the time between Aikman/Romo (of course we do-you keep equating losing the current QB with going right back to those years as though this team and those teams have lots in common apart from who is playing QB), you think you can just plug a guy in and begin winning 12 games a season (of course not-this team is on a two dimensional circle track and the QB is entering his 9th year-you don’t think it likely he and this team have gone as far as they can together?), you think good QB’s just grow on trees (no, plenty of okay/good QB’s land on good to average teams and have decent records though perhaps just missing the playoffs).
The fact remains that with this QB’s current list of postseason exploits, that the team has basically a zero percent chance of even reaching a conference finals game let alone a Super Bowl (all-time NFL historically speaking). He is almost guaranteed to not be a starter five years from now-or a greatly diminished one. Most QB’s do not make it to the age 40 season-no matter if they are exceptional prototypical pocket passers or not (and that is not this QB’s game and never will be).
