gotta say I think I'm on board with Mark starting this year here's why.
Let's get all of the cap pain out of the way in 2013.
With Mark and Rex I would not mind if the season totally tanks.New coach,qb,possible gm depending or not if Woody brings in a puppet next year
then among the top draft picks next year,Clowney,Bridgewater,and possibly Johnny football (think Russell Wilson has opened the door for short qb's)
There is no doubt in my mind Sanchez will be the starting qb next year.Rex won't start anyone else
