And to put and end to this "debate", these are mid-season projections for David Johnson
http://www.foxsports.com/nfl/story/...-stats-historic-start-yards-touchdowns-102416
With 1,004 yards from scrimmage and eight touchdowns through seven games, Johnson is now on pace for 2,295 total yards and 18 touchdowns.
Only twice in NFL history has a player had at least 2,250 yards from scrimmage and 18 touchdowns: LaDainian Tomlinson in 2006 (2,323 yards and 28 touchdowns) and Priest Holmes in 2002 (2,287 yards and 21 touchdowns).
With your little brain, can you even fathom what Johnson is doing in Arizona right now? This is behind an average to a little above average offensive line, if that. Yes, yes he is far and away better than any RB in the league right now. He's essentially the running back and receiver on that offense and biggest reason for the Arizona turn around since their rocky start.
If he has a couple more big games when it comes to TD totals, he will be on pace to an LT MVP-like year.
