There is simply no way you can make a valid comparison of teams in the 1920's with teams of today. Weiss is doing what any smart coach would do. If you're facing a team with a great pass defense, keep it on the ground. If you're facing a team that puts 8 in the box, air it out. As Sun Tsu said 3,000 years ago, if you know yourself and your enemy, you need not fear a hundred battles; if you know yourself but not the enemy, for every victory gained, you will also suffer a defeat; if you know neither yourself nor the enemy, you will succumb in every battle.
