Samaris doesn't have a team, before being let go for free by Benfica he basically hadn't played at all last season. Not to mention he's always been bang average to poor for the Ethniki. Fortounis is injured, so unless we roll him out on his crutches probably couldn't have played.
Won't deny Sokratis and Manolas would've helped during this campaign, they have had off-field issues with management that has unfortunately ended their NT careers as long as JVS is at the wheel. But half the guys you mentioned it's not feasible for them to be playing currently.
Samaris is done with the NT, he needs to find a club and he wasn't able to find one over the summer, clearly his career is winding down.
Stick to AFL re, Blues for the flag next year Cerra to win the Brownlow.
