I do not think their is a lack of coaching experience but more a lack of game coaching experience. It all looks great on paper until the defense punches you in the mouth and you have 15 seconds to call the next play and then 15 minutes for a back up plan at the half.
Those conversations is some of the most I have ever learned as a football coach. The "what if" questions brought up some great adjustments and ideas which helped down the line and lead to a lot of success.
Do you think they installed the entire offense this season or are going in baby steps because the offense is so different? I'm curious if the coaches had the foresight to see that not only were they at a disadvantage with the talent level of the players, but they also knew the new playbook was too much to install in one offseason, especially with the older players stuck in their ways of playing in a pro style scheme. It almost seemed like they had to almost rewire the players thinking so they'd to see the game the way the coaches do before installing anything.
