If you watch sportscenter every team that doesn't have a QB named Brees. manning or Rogers has a QB controversy/competition. stop listening to that crap and just watch the games. You'll feel better. Sanchez is fine with the system. If Tebow helps win games early,,,,the pressure is off Sanchez and he keeps his job.
It depends on Sanchez's play. If he plays well and they are winning he keeps his job. If Sanchize isn't doing so great, and then baby Jesus keeps saving the day, baby Jesus's role is going to expand, and quickly.
A good QB doesn't care how good his backup is. He knows his job and takes care of business. That whole "it will ruin Sanchez" thing is so overrated.This whole QB to challenge Sanchez thing is a joke. Tebow is here to bring another dimension to the team, Not to threaten Sanchez or scare him into failing.
