The best champions not in lane to counter Thresh include Kai'Sa, Ziggs, and Zeri. These are all great at countering Thresh with decent win rates over 57%. Even if these Thresh counter picks are not used in the same position as you, it's not a good idea to play him into these matchups. They will very likely crush Thresh.
Yet, if the opposing team picks either Rumble or Brand, Thresh mains should seriously think about selecting him, as he easily beats these champions with win rates over 52% against each ofthem.
