this is a retarded question tbh, if they were to play tomorrow, val teams would 13-0 cs team in valorant and cs teams would 16-0 teams in cs, maybe they could get some rounds if they troll but if teams played all rounds full focus easy 26-0 and 32-0 no doubts, even if most valorant pros were ex cs players, these are top5 teams and without any practice as a team no chance you even get a round + most val pros were tier5 in cs too
it gets interesting tho if we give time for cs pros to learn valorant, they would probably beat these valorant teams if they had the same knowledge and experience in valorant, they are way more talented players, they are literally the elite among the elite
