Two things that are pretty important to this discussion that most people either don't know or seem to gloss over;
First, the first draft for KAM and the new regime, as is customary when there's a HC and staff firing, was conducted using the entire scouting department, and their information and insight, from the previous regime. This is typical in the NFL, and then most or all of that scouting department is sent packing often immediately at the time of the draft or just after, and the new regime brings in their own scouting department.
