Who are the Walking dead's Protagonist, Deuteragonist, Tritagonists?

I was looking over the walking dead articles recently, and noticed that in the first season of the video game, there were three main characters, Lee was the playable and lead character, clementine was the deuteragonist, and the tritagonist was kenny. And when i saw that, it made me think of the walking dead mediums and i began wondering who the main three characters (loosely) were. now, i realize that the walking dead's cast is usually made up of an ensemble cast, but thinking like this, i always thought that in the tv show, it was rick as the protagonist, carl as the deuteragonist, and rounding it out was Daryl. while in the comics i thought that andrea toke the role as tritagonist while carl and rick stayed in place. but i want to know what you guys think?
