I despise Skip just because of his annouing ridiculousness so I won't even watch the video. IMO, without a doubt the Cowboys are easily still a SB contender without Zeke. It's really not even a good argument. To sum it up, we have so many weapons and a great O along with 2 "backup" RB's that could easily start for other teams and would do a good enough job to help get us there (along with Beas, Dez, Witten, etc).
If they want to worry about the SB, the question should be if the defense is adequate enough to get us there. That's debatable, the offense isn't.
