I'm guessing Ryan won't make it through half the season if they start the way they ended last season. I doubt that management will tolerate the dysfunction again.
Tebow might add something...But it won't be dysfunction. It's already there.
Ryan seems to thrive on dysfunction...But it's a lot easier to tolerate when you're winning.
You don't think adding a QB who was the starter on a team that won a playoff game last year, and who has a lot of fans who will want him to start, to a team with a fragile starting QB position already won't cause more dysfunction?
As the old saying goes, if you have 2 QBs, you have 0 QBs. It is going to be a bigger circus than ever this year, and by bringing in a guy like Tebow, who is not good enough to clearly take Sanchez' position, but is good enough to make him uncomfortable, will just be another distraction for a team that needs stability if they want to get to the next level.
