31 down, 1 to go. (2 if you count the fact that we need a writer for the Baltimore blog)
SB Nation is getting very close to filling the entire NFL section of the network. With 31 NFL team blogs now apart of SBN, there is only 1 left to go before all 32 teams are represented. The 31st and newest blog is Revenge Of The Birds, which will cover the Arizona Cardinals.
Detroit actually plays Arizona in November, so I'm sure you'll hear more about the new blog then.
