Hard comeback wins! Why did my team win?

Ok, so in champion select things got a pretty hostile, but we managed to stop it and be serious...so no trolling ensued.

After being behind in the mid game, we held out after they grabbed baron and an inhib, then WE took baron using Tryndamere split pushing tactics, and then won some key team fights and managed to end the game..

I also happened to upgrade my trinket. Speaking of trinkets, I checked post game statistics, and we placed 109 wards vs their 66.

Almost double the amount of vision on the map than them.

Makes me think that we were able to make some key decisions because we had vision.

Vision op boys/girls!!

P.S. me and Ekko carried lmao our tream tried surrendering twice but we said NO!!!
