Arkansas' begins on March 16 as announced last week, and the spring game is on April 25. Tennessee is the only other school playing their game on the 25th. I'd expect many of these games to air on the SEC Network (or at least SEC Network +).

I do think it's interesting how different schools organize their spring practices. Some like Georgia and South Carolina go through the whole thing in three weeks, while schools like Arkansas spread it out over 6 weeks. You'd think there'd be some sort of consensus on what the best strategy is but there isn't.
