Charlton are 15th and Blackpool in 14th, I don't think there will be much to seperate the sides and the best odds are to take the draw. The bookies are leaning that way with their odds.
Charlton have drawn 3 out of their last 5 league games at home to mid ranking sides Huddersfield, Brighton and Derby only losing once in their last 6 homes games to Ipswich.
Blackpool have drawn alot of games since change of management as they have drawn 7 out of their last 12 games.
I expect honours even here, score possibly 1-1 so worth correct score punt on this too.
