Madden 13 sold 4.75 million units. NCAA 13 sold more than you suggest, it moved around 1.5 million units.
My original point still stands that saying "NCAA Football is second most popular sport in the country" is overrating its market size in video games. 1.5 million units is pretty good especially for a sports game, but 1.5 million is is just a small percentage on college football fans. My point also was despite its huge fan base in real life, it isn't the second most popular sports game, as Madden, Fifa, and NBA 2k all sold more last year.
Also I think your confusing me with someone who thinks EA will stop making NCAA because of sales. I haven't said that and have definitely disagreed with it in the thead. Only way NCAA stops being made because of sales is if the outcome of the lawsuit allows EA to keep making it but only with randon, generic characters.
