I'd add the values on RES and AGG are also overblown, like many players of that time (defenders included) he wasn't really "agressive" on the opponent player, he waited most of the time for the player to come to him, something like 77/78 in RES is enough. And concerning AGG, yes he could join the attack every now and then, but it wasn't like Cafu, Roberto Carlos or recently Dani Alves. I have him at 75 (might be a point or two more at best) in AGG, he was dubbed an "offensive" side back in a time when other side backs had nowadays CBs playstyle, while they NEVER crossed their own half but that doesn't mean he was a machine to go forward and back on his flank in 90 mn. Same for Nilton Santos who still was a bit more attack-minded than him but nothing extraordinary by contemporary (Brazilian) side-backs.
If I dare to make a comparison and put things in perspective, I'd say Marzolini was more or less as attack-minded as Alvaro Arbeloa is
I have mostly seen him in the 66 WC as footage from Boca is scarce, but even on the few vids I've seen concerning Boca he wasn't pushing forward in a regular basis to get 88 in AGG.
