@maxim Really depends on what exactly you mean by that tbh.
If by "tackle" you mean actually grabbing someone then I would say "anpacken" or just "angreifen" (as in "attacking") Main issue here is that it's a term based on American Football so often just used as "tackle" by Germans too. I wouldn't think of "schleudern" for "tackle" tbh. as that's more "throwing" something than actually grabbing someone.
If you mean just as a general bumping maybe "stoßen"?
