re: How hard is it to understand, "Miles' offense" isn't the problem. Having a QB is

Throwing deep is low risk and easy for a poor quarterback to read. All he has to do is maybe see where a safety is going so he can look for a 1 on 1.

Throwing medium range across the middle requires reading LBs, safeties and the occasional dropped back DL. That requires skill. We don't have that at QB.

That is why we suck at passing.
