i don't do them anymore but did Joe Rogan for awhile (his podcasts are awesome), and colin cowherd for along time.
colin is good because during football season its all football, during march madness it's all basketball, and he basically ignores all the other sports in between and chats about normal shit people actually care about instead of having a summer of baseball statistics. he's dedicated like 3 shows in a row to the last episode of the sopranos which inspired me to go watch the series.
