Wait so there is all the alliance and navi players + commentator (toby?) + someone between Akke and Loda who I don't know.
The 3 people carrying one another on Alliance side is Akke, S4 and Loda (from bottom to top). Their roles correspond with the Na'vi side (Akke and Puppey both supporting the solo mids, while the carries are on top) 
I like how you know everyone except the team captain of Alliance.
it's S4
