Based on your logic, we should just be able to take MHJ's game 2 and 3 to say he was going to have 1,700 yards and 15 TD's for the season.

On the flip-side, let's look at McBride's first three games, where he totaled 125 total yards (42 yard average per game).
You can't judge a player by a few games played vs others who played an entire season. You know that.
