well it actually depends on the champ u pick and how fed you do get.
kalista and vayne can carry games ez(u gotta be gosu if u wanna carry with vayne tho)
in supp it just depends on the adc if you can help the destroy lanes and if you can defend them or have amazing initiations for the team. the best supps are naut and alistar.
Mid lane can carry with many champs, yasuo, viktor, kog, etc.
It doesnt really matter which jungler it is but if that person gets all the lanes ahead or do amazing in teamfight. i wouldnt really call it carrying but whatever.
and in top lane the 4 i can think of on the top of my head r fizz, maokai, rumble, and gnar but a new patch comes tomorrow with a few big top laner champ changes so that might change(i think darius will get on the list of top champs to carry with)
oh and here a yasuo game #DAMAGE
