I think you're on to something JHS was putting up footage too wasn't he of running up the dunes? On top of @KareemtheGreat33 's theory of no meat not helping him.
the reason i know vando isn't coming back from injury soon is that he's being leaked as trade fodder. i view him as, like dlo, a "more important to us than them" type of player, so if we've decided to move him, it means he's not important to us anymore, either. i think this only happens if we think his injuries will never go away.
