We have dumb players for sure.
We've changed the playcaller... and still the same old shit.
That only leaves the system. And everyone says that Garrett's system is the easiest system to figure out and the most predictable.
On offense, we could have the best player at EVERY POSITION, I'm talking Peyton Manning at QB, Adrian Peterson at RB, etc. and these coaches would still crap the bed with the playcalling.
