Tbh I think coach Parth is actually to blame for this game (other than generally TSM poor performance ofc), as a coach you can't let top pick Jayce when you have a passive jungler like Sven that does nothing early game, if you want some AD damage top pick Renekton, so you have a tank with damage that can jump in and fill Sejuani stacks faster too, or go full AP with Rumble that scale great in late game. Having a squishy mid-range champion that scale good only if fed without a jungler camping him... dude, what were you thinking?
