First of all, both Spencer and Jarom are on CB pretty regularly (even though they think CB is a waste of time). But beyond that, there are other reasons for CB topics showing up on SportsNation.

Apparently, they have a meeting early each morning where everyone has to present at least one topic idea. The students in that meeting have a wide variety of interest in sports; some just are doing an on-campus job, while others are hoping to go into sports journalism someday.

As you can guess, it's pretty common for those students to troll CB for topics (especially when they're busy or aren't all that interested in sports to begin with).
