According to Zombs, Riot took money out of the prizepool during champions. Each team was supposed to get $20K, with each player getting around $4K each. Zombs said he walked away with around $1K. Even with Org fees this is pretty abysmal from Riot after making all that skin money from champs.
Edit: This also means that the rest of the 9-12th positions got around the same or less including Envy, Vikings, and, Vision Strikers.
