Your reasoning is logical. However players heal differently.
Gallup had acl surgery on Feb 10th, was held out the first 3 games and had a less than impressive recovery year once returning.
Chris Godwin of TB had the same acl surgery a month previous on January 3rd.
He played in the opener but tweaked his hammy. Sat out the next 2 but played in all weeks 4 -17.
He caught 100 balls for over a 1k yards.
So yeah, some players heal faster and more effectively than others.
My prob here is those who criticize opinions of heal time and effectiveness guess work as though they are doctors.
Not you, but in general.
And it's been my experience here that a publicly reported time to return may not end up being exactly as first reported.
