OMG first picks Janna in game 5
With Thresh available - who in the previous game was a major factor in their win.
SHR picks Thresh themselves while OMG place Rumble to take on a 2v1 against hooks. Thresh easily sets up first blood and early game dominance with lantern ganks which leads into an easy mid game and win.
I dont believe games are truly lost in picks and bans........ but OMG picked their own defeat right out of the gate for seemingly no apparent reason.
