A West Coast offense does not mean to throw the ball on every down.
The idea is to throw first to open up running lanes. Well...we throw, but we never run. When ahead, we throw. When we're tied, we throw. When it's 3rd and 1, we throw. When it's 2nd and 14, we run.
It doesn't make sense. Pull up the stats and we only ran the ball 3 times in the second half up until the goalline.
Look at the win-loss totals and you will see that Packers chances of winning were over 80% when Grant ran for 20+ carries and Rodgers threw for less than 32 attempts.
I love Rodgers, but lets face it, he's not Peyton Manning who can throw 50 times a game.
