Rutherford was good, but Dickerson was mediocre. I'm simply pointing out that they have tried to recruit athletic black QBs, athletic hispanic QBs, and athletic white QBs. Many have not worked out. More recently, Chapman was highly regarded, but never made it to campus. Voytik and Anthony Gonzalez were also well thought of recruits who just weren't good enough. Rutherford and Palko fit that mold and were good.
They've offered a good bit of dual threat kids, but haven't landed them. They haven't landed many good QBs at all.
