Just as fans. I am sure Reich has a way to determine that improvement and what defines success toward that goal. From what I recall, he said top 5 (or maybe top 10) run game...but he didn’t elaborate on what that means. It could be ypc...yds/game...total yards...% on certain downs...or some combo. I am just curious to know what success looks like to him...and the plan to get there.
Real NBA pundits, coaches and execs were parroting "Jump shooting teams cannot win in the NBA" and "You need low post presence to win" just like... 5-10 years ago. Data and analysis about the value of the 3 has been available for close to 20 years. You underestimate just how married people are to their old ways and how hard it is to teach the old dog new tricks, especially when this is all they've known for their whole lives and they've had success with it for their whole lives(mainly because everybody else was doing the generally the same thing) and now you are telling them what they've been taught for 20-30-50 years is wrong. Some will adapt and flourish, most won't...
My favorite quote that encapsulates perfectly the situation comes from a field that is MUCH more open to new ideas than football - science. And even there, there is a long history of resistance to new ideas. Physicist Max Planck once said "Science advances one funeral at a time". What he meant was that science doesn't advance by convincing the old guard that the new ideas are correct, but by the old timers just dying out and the new generation unburdened by emotional attachments to the old stuff being allowed to just follow where the evidence points to.
BTW I do NOT think the run game is meaningless or that it doesn't have a role to play in today's game. It is extremely important in situational football, in end of game situations, in goalline and 3d and 4th and short situations, etc. I just do not think it serves anyone any good perpetuating myths about its importance for things that have been repeatedly shown to not correlate to run-game success.
