Remember all the angst about 1st down runs.. lol
More than the Jets game
It only means something when it means something. In other words it is a predictable trend because you make it a predictable trend.
The Cowboys in the 90's ran on first down at an extremely high percentage during the Super Bowl years (1990-1995). However, they had an OC that knew what to do on 2nd down. Cowboys were rarely in 3rd and long.
1st down percentage is a sucker stat. It is what will you do on 2nd down matters most. Most of the time Norv Turner was going to call a dump off to Emmitt, short pass to Novacek, or on 3rd and short a pass to Novacek. If 3rd and long, slant to Irvin. Everyone knew it was coming but could not stop it. Because Norv called plays to get in position to make first downs, then strike to the WRs.
On second down Boy Genius or the Clapper are trying to throw to the WR +10 yards down field instead of picking up 5-7 to the RB or TE to convert 3rd and short.
Football ain't rocket science.
