The term curtousy visit cracks me up when it comes to officials. The school only has so many officials per cycle and they wouldn't waste one if they knew there as zero chance for the recruit signing. Likewise the recruits only get 5 officials; why waste one on a program you aren't considering.
The fact both will come in for officials shows we have a shot, no matter how small it may be. Nor does it matter that the only reason they're interested in USF is their former coach. Getting them on campis for an official is huge.
