Three points.
1) Bledsoe is unbreakable. I think we won't even sniff a backup on the field during the year. The guy stayed healthy with one of the most atrocious offensive lines (outside of the Texans) last year, gets sacked more than any other QB, and yet still fails to get injured. Tom Brady took that one in a million chance of him getting injured and ran with it.
2) The #2 position on the Cowboys is still up in the air.
3) I think Romo and Henson will fight for the latter, and we have the same three QBs on the roster next year as we did last year. I think the coaching staff believes in both of them.
