These days, the letters and e-mails arrive in the Georgetown athletic department by the bundle, all wanting to share a story with Austin Freeman. “You’re an inspiration to people with diabetes, I’m looking up to you now. ...” The strangers all want the Hoyas junior guard to know that playing with diabetes isn’t uncommon. That it can be done. That it’s not as big of a hurdle as it might appear. That there’s now a whole big network of support open to him to pick and peruse. Freeman, though, is just trying to figure out one thing: Diabetes itself. “I’ve gotten e-mails and stuff from people telling me they have diabetes,” a reserved Freeman said in the Hoyas’ locker room after their 69-49 win over South Florida. “About how they’ve played college basketball. About how they’ve played college sports. But I mean, it’s good to know that there’s people out there that care. And that I have support.” But since news of Freeman’s diabetes was disclosed last week, it’s been an overwhelming couple of days.
