THIS.

I'm amazed when I hear that the defense "needs time to adjust to the new scheme," and its something like playing zone defense.

Have they never run a zone d before? From Pop Warner, to high school, college, and then pre-season I am amazed at the learning curve many of these gents display.

These men are supposed to be professional, masters of their craft, literally the most capable people on the planet, and they can't figure out how to execute a)clean tackles and b)coverage responsibilities in a zone scheme. (and please don't respond with "they're not hired to be smart, etc") because lots of these guys are very intelligent men.

I mean c'mon, there's only so many ways to put men in motion before the snap to disguise/reveal coverage duties

Someone please help me out if I'm missing something here
