Maybe so but he shouldn't be suffering such losses, they're all mainly due to strategic mistakes, Russia don't seem to be running any sort of air patrols and they're incapable of surgical strikes on Ukraines air defences, it's utterly insane they will fly troop transports alone to their targets when 50% of the Ukraine air defenses are still operational. They're sending armoured units in Urban areas with little infantry support, it seems there's a massive issue that there's one plan that everyone must stick to, that has specific limitations when it comes artillery and bombardments and if it doesn't work there's no plan B or C and they're just trying to brute force their way through.
Likewise there's issues of logistics with fuel & food, there seems to be no supply line or security for a supply line, you don't need to be an arm chair general to know these are basic military essentials, this isn't a last push of units in order to try & capture supplies because the enemy has decimated your supplies back home ala Battle of the Bulge, there should be zero reason they are running out of fuel & food.
No matter how this ends this is an utter embarrasment for the Russian armed forces and will be analysed for years on a "how not to" conduct a military operation
