It was the beginning of the tension between Garrett that eventually resulted in Callahan making a lateral move to the Skins.
You answer neither.
I have always stated he's not as bad as most state but that he is imminently replaceable as being somewhere between above average and good. But no one has yet displaced him although I remember Parnell and Free both playing RT at one point interchangeably. Parnell moved on and Free stayed. I remember Callahan stating Parnell could play in this league and I remember you and I being moderately vocal about both players being good enough to play RT for us.
I do not remember Callahan benching or wanting to bench Free for Parnell excepting when Free was injured too much to play.
You're clouding the issue which is Free has played well enough to start for the Cowboys since, without looking it up, 2009. If they can build this OL then I'm going to assume they know what they're doing. That defeats any talk about playing Free as the starter at RT.
