Reading the scrimmage notes it must have been ran like the spring game with the offense at least. All the starters named on both sides of the ball dominated. The starting O line was said to be good but the defensive starters had a bunch of sacks.
That's the tough part - gauging how good a unit is going against teammates. If the O-line is bad, the D-line dominates and looks great. If the WR's are bad, the DB's look great. I agree that all positions appear to be better, but how much better will start to be determined vs. Miami.
