Nathan never got that great storylines either. You could argue that he has this thing with Dan, basketball storyline, etc, but they were all half assy done. Lucas also had other storylines other than being the center of love triangle, like his relationship and rivarly with Dan, problems with heart, mourning Keith, the writer career, the coach career. Sure they were badly done, and writers didn't really focus on them for more than five seconds, but were Nathan's storylines any different? But seriously, I don't think any of the character got a real focus except for Peyton and maybe Brooke in later seasons.
And Mouth of course!
