With the 42-17 win over the Detroit Lions, the Arizona Cardinals didn't have a lot of offensive snaps. In fact, there were only 46. How was that time divided? Have a look.
Palmer managed to throw three touchdowns in 33 snaps. Nicely done.
All this tells us is the game was so out of hand they even used the second team offensive line for a couple of series.
Johnson played 17 snaps and had 11 carries. When he is in the game, he is being used. It is also interesting to note that the offense started moving when Johnson was in the game and being used.
