I ship them but not because of Puckleberry, I just think they could be a great couple, also eve if Jake were like Puck, Marley is not like Rachel, she's so diferent, she 表示する it since the first episode.
I don't ship them because of the resemblance, but I see where you're coming from. They couldn't give us Puckleberry, so they gave us Jarley to compensate. The bad boy and goody-girl getting together. It's become somewhat of a trend these days ..not just for glee/グリー but all fandom. Maybe Marley will do good for him, mend him. :3
