Will Moss get cooked in man coverage with 80 agility?

I‘ve never known if agility makes a difference/means anything for players in coverage. The new moss CB looks great but for some reason seeing the 80 agility just makes me think he’ll get cooked on cross routes in man and I don’t know if that’s actually true or not.

I’ve thought this way for years now- Jalen Ramsey has 86 agility this year,  but in the past he’s always been one of the best day 1 corners and he usually has around 80 agility as well. I don’t know if it’s just placebo or if it actually makes a difference, but I can’t decided if I want moss at FS or CB for this reason alone
