I agree....and this is coming from a Diehard cowboys fan and a huge supporter of Miles even before his breakout season.
Miles Austin is clearly the best receiver on that team....but the first two games it seemed Romo kind of forced the ball to Austin underneath a bit. Romo is at his best when we spread the offense and he spreads the ball around, and that's what we saw in the win against Houston. If the Cowboys offense continues to spread the ball around (it should but lord knows what Jason Garret will fuck up with an extra week of planning), Austins numbers could go way up or way down depending on the night.
I would still keep Austin over Calvin. I always look at the QB situation...and Austin is in a good situation.
