Not to argue, and certainly not to defend BF, but ...
If you were a CFO for a large, complex business and the company hired a data analyst to provide you with better information - he would be in a position of "helping you", but not teaching you how to be the CFO.
If I had to guess, I'd say the Analyst is charting the formations/plays that have worked against certain defenses and ones that don't - and things similar to that.
For example, I've always wondered, as most fans have, why Iowa simply doesn't have many open receivers. Perhaps he is tweaking the pass routes for better timing and coordination. For example, if there are 3 guys in the pattern and the play is designed so all 3 are "supposed" to be open at the same time, the QB doesn't have a progression to look at. But, if one guy is open in 3 seconds, the other one in 4 seconds and the 3rd is open at 5 seconds (just examples), the the QB can go through an actual progression and find the open guy.
The Hawks have had poor results on offense - I don't think it's simply because of SP or the line not blocking or a bad play call. I think Iowa has a poorly "designed" offense that even a good offense would struggle with. Maybe the Analyst can bring the offense up to date.
