We must be playing a different madden. There is not a "Run Heavy" Scheme. There is a run heavy playbook, but not scheme. I checked repeatedly in hopes I had just overlooked it. >_> Not funny.
And I've used the run balanced pb quite a few times and the balance between it or the Seattle seems the best choice. I ran a test sim at 20 / 40 and it also seemed to do good in terms or runs. Peterson managed to get up to 330~, Bridgewater was 540~. Guess I'll just have to accept that a true run first team is going to be difficult this year, unless I play a large portion of the games.
