With new trailers for Thunderbolts and Captain America 4 out over the last couple of months there’s been a resurgence of “Bucky should have been Cap instead of Sam” opining, with one of the main reasons given being “Bucky was Cap first in the comics!” Sure, he was, it’s true (mostly – there’s an issue that’s published after Bucky’s Cap run but takes place before it where Sam takes up the shield while Steve is briefly incapacitated, but that’s a somewhat flimsy counterargument), but there’s an awful lot of nonsense that happens in the comics that shouldn’t be used as precedent for the movies. More importantly, if you’re talking about story then the circumstances in which Bucky became Cap don’t support the argument themselves.
