Most of the sports subreddits are pretty awesome. /r/cfb is my favorite, but /r/baseball, /r/hockey, and /r/fantasyfootball are all quite good as well. /r/nfl is probably the flagship sports subreddit, but it has been a little rough lately with the community and mods having some conflicts about the direction of the subreddit.
Lately I have had a sad feeling that r/nfl has reached an inflection point where it is quickly degrading into just another large subreddit. The firestorm surrounding the NFL's domestic violence issues this season seems to have had permanent effects on r/nfl.
/r/nba is also awesome, along with literally every individual NFL and NBA team sub I have ever visited. Most are quick to ban opposing team fans for anything resembling trolling though. Tread lightly.
