I don't get some of the sarcastic remarks to this comment. Erving, Williams, Looney, McGovern, Martin was much more effective than Knight, Williams, Looney, McGovern, Steele. I think that was pretty obvious just watching the Vikings game, then the game against the WFT. So, Erving did not do a bad job filling in for Tyron Smith. Absolutely a true statement. There is no further meaning in it than that.. No one is suggesting he makes the Cowboys a playoff team or that he will be the reason they win the division. Be he did not appear to be a major weakness, like say Chaz Green.
I actually think, if by some miracle Martin and Erving can make it back for the last two games against the Eagles and Giants, the Cowboys could win both games. They certainly have a better chance with them than without them.
Even if just Erving comes back and Knight goes out to RT, I think the Cowboys OL is better. Steele is just not ready to be a starter yet.
