I'm really impressed with the guy, Coach Canalas-But to keep this short....(Because I could really expand on this with alot of TDLDRLRTD'ed) I'd rather keep it short, sweet and simple.
Fun. What he and Dalton really expands on alot of... underneath all the schematics, engineering of a playbook, contracts, grueling practice, sweat, tears and nagging pain, ibuprofens..,etc... Is bringing it back to why we played sports in our pee wee leagues. Because it was dog gone fun.
Pyschology of Fun on gameday.. Pretty easy to grasp, but this conduces looseness.
When you've learned something through basically muscle memory, the last thing you really need on gameday is the calculator robot without emotion. We are human, Emotion and fun of winning brings a locker room up faster than any large paycheck to the leagues best player or in other words, It's genius to lighten up.
Canalas does this naturally. Dalton does this naturally. These are guys you want to go out to eat with. Hang out with. They're fun. Before football, we're human.
How do we win as humans? trustworthy, loyal, helpful, friendly, courteous, kind, obedient, cheerful, thrifty, brave, clean, and reverent.
The obvious factors of knowing football are I believe pretty given at this stage of the sport.. The "IT" factor for this era, I believe, is their engineering of football X's and O's, but intrinsically the guys you have fun with.
