I'd guess its on Primetime because thats what happened when a totally unconnected card started losing undercard fights a couple of weeks ago....
Joking aside, I think it would reflect Dave's image, if we get a bit of 80s/90s British ITV Saturday night/Midweek Sports Special boxing on there. I know they have it on other channels, but Dave is one of the less obscure other channels. A bit of Second's Out would not go a miss either...
