Agreed and this is why I compared him to Stewart, who is also an outstanding loose defender but could not be considered a lockdown player. They are still very valuable but by definition a key defender should be 10/10 both at 1v1/lockdown work vs the best of the best AND elite intercepting/rebound ability.What you are describing is a loose defender not a key defender. Rance was arguably the best loose defender considering how much he did it, but when McGovern played loose I think he was even better. The best loose defender in the game right now plays for my club I think.
Key defenders are accountable for their opponent. The best key defenders are accountable for the best key forwards. For peak rance period, that was usually Astbury taking the best key forward.
Having no stats on two key players though (lep and scarlo) really sucks though. Especially since I just feel like Scarlett is my pick.
