It's very clear from what we see as fans.
Fans aren't getting the whole picture, that's the point.
You're just speculating as to something that's impossible to disprove.
I'm not doing anything, other than saying, perhaps Mike McCarthy knew better than you given that
a) he knows what the fuck he's doing, actually, and
b) sees all the practices himself and you don't.
Sure it's possible the guy has basically just finally had the light bulb turn on just at the same time he hits the field.
It wouldn't be a "coincidence," that the guy has the light bulb come on the "same time he hits the field." He hit the field BECAUSE the light bulb came on.
And yes, that is speculation, because I don't know, and neither do you. But it's a possibility that perhaps makes more sense than assuming that McCarthy was just sitting him for.... reasons.
Even though we all have seen, heard and read things that showed us he was this type of player long before he got his shot this season.
We all saw, heard and read things that indicated he had promise. Not that a sixth round pick from last season was ready for the full time role.
This isn't difficult to see the Cowboys should have had him starting at the begining of this season.
We simply don't know that.
