I generally agree with your post till we hit your faulty logic re Cigs.
Why would you consider the Salary Cap in the Aggregate but not the use of Players in the aggregate.
The fact that Tavon got 9 TDs in 2015 when the offense stunk I think makes the opposite point that you are trying to make when you consider it in the aggregate:
17.5 ppg, 29th out of 32 teams on offense.
When considered in the aggregate, McVay knows how to use everyone better towards the ultimate goal of Winning Football games.
I don't think you prove you know how to use players best, when in the aggregate, your offense sucks.
