I have to go with a combination of the two. Under Renney's 4 yrs we were ranked 8,8,22,29. Under Torts we were ranked 13,18,23,23. Needless to say that player personnel changes occurred that changed the dynamics of the special team and their results. Renney going from 8th to 22,29 and Torts going from 13 to 23. However you cannot rule out the system that each coach brought into play and their failure to modify their systems with the player personnel in place as changes occurred. Like with AV going from a same personnel showing of 23rd under Torts system to the current 7th place showing under AV's system.
