Interesting and informative post!
The west coast offence is predicated by the fact (belief) that it is easier to complete a six yard pass rather that gain six yards running the ball.
Also to be successful possesion type recievers who don't drop the ball are required.
The recent WC offense tendancy has resulted in many more 3-4 defences that are stacked with speedy LBs who can get into passing lanes to break up those 6 yard passes.
Personally, I don't like the WC offence. I like the Power running/ play action type of offence played by Indy and the 90s Dallas teams. I think the WC offence is too easily disrupted by speedy defences (Baltimore and Tampa Bay did it too us- Ugh).
I am glad we are moving back to a more vertical and ball pounding offense.
