I think I get what you’re saying, but even still, Saints have at least 3 of their top flight players out, all who play in important structural positions (not to mention Steele’s leadership).You can’t play 30 players every week. A team that’s 4-1 and on top of the ladder after several years of middling is a lot closer to full strength than you’d think.
So even with just 3 out, that itself puts them way off being at full strength.
