One thing you have to remember is the players were split up due to the draft format, so you did not necessarily have guys playing in the same units they have been practicing with. That makes a difference, especially for the O-Line.
Important for the coaches to identify a 1st team and 2nd team o-line, and get them lots of reps as a unit to build some continuity.
Same holds true on defense - the top defenders were split between the two teams, so you didn't see a true #1 unit out there. I think there are some play-makers on defense, which will hopefully be more evident when you have a true 1st team and 2nd team setup.
And the punting game - at least tonight - stinks on ice. If that's the best they can do, it might be open tryout time. Unless one of the incoming FR can punt a ball more than 30 yards.
