Romo could be a solid QB here for another 5+ years under the correct system. This isn't like the 80s and 90s were QBs were concussed out of the league by age 35. Romo is an athletic beast, and he can thrive for awhile still. Now, SF has proven with Kaepernick that you can develop a great QB quickly these days if you have the right coaching staff in place. It's way too early to starting thinking about the next QB. Lets get Romo an adequate Oline and HC and then let him go out and win some games.
