I do agree with this but those are in the offseason, as for Kucherov his timeline realistically fits what's needed... if he's within days of returning early it's easier (not right though) for them to milk it out, especially it being a long-term injury from hip surgery, even once he's back he won't be 100%. As for Andersen if it truly is 7-10+ days it's not realistic that they could milk out 5+ extra weeks without being deemed fit to play from a short-term injury.
Hopefully the injury either expected to be long enough that they can safely place him on LTIR until playoffs while adding, or it's just a minor 7-10 day injury; nothing in between the 2 is any good. Something that's expected to be 7-10 days just seems like to much of a stretch and would likely be investigated if they were to attempt this.
