I question the phrase "effective" being used with Tanner.
I don't think the drop off from Murray to Tanner and that from Romo to Orten is that different.
I wouldn't want to see Tanner for a series or two anymore than i'd want to see Orten for a series or two.
That being said, if you're going to have standards, they should apply to everyone.
So will Tony Romo be benched after his first interception of the
season? DeMarco Murray: "I highly doubt that."
notice he said season and not preseason. Murray would not of been benched for one fumble in regular season either. If he had, then you have to question why the coach trusts him to be the #1 guy at RB if you cannot trust him to recover after a fumble and make the other team pay for it.
Murray is just stating what is expected of Romo and the trust that Garrett has in him as a QB. If you asked Romo the same about Murray if after one fumble, would Garrett pull Murray in regular season, Romo would say the same IMO
