that as a mark against him NO DOUBT.
NFL scouts can also see EASILY when someone has skills and their coach(es) have not utilized them correctly (HELLO Fred Warner, thank you for entering the chat!).
I have no problem with Holker leaving as he gets to make his own decisions for whatever reason he wants. **IF** he is leaving to help his NFL prospects then he either has been getting some absolutely terrible advice or he's less than smart.
