If WRs are dropping passes (in practice or games), not blocking and half assing routes, it’s a sign and by product of their lack of belief and excitement with the OC and scheme.
If DBs are lost, staying on blocks, blowing assignments and missing tackles, then they lack belief and excitement for their DC and the coaching they are receiving. These are the two positions (the most vocal and emotional) that show mutiny against coaching first and these are the signs.
This group looks engaged, urgent and well coached.
