Didn't have a summer camp? They had the elite camp in June and he's getting ready to host a coaches clinic, may want to check your sources.
As for not recruiting, he's not Pearl or Tyndall, he's more Martin, he doesn't leak things to the press about recruiting because he doesn't give a crap about what the general fan feels they should know about recruiting. They hosted 4 official visitors for the Oklahoma game as well as unofficial visitors, they are set to host 2 more official visitors this weekend, and have another offices visitor tentatively scheduled for the Georgia game.
Jordan Bone who visited for the Oklahoma game committed that weekend, Josh Okogie who visited that weekend is set to announce 10/14 and most like Tennessee, they missed on De'Riante Jenkins who visited that weekend, and they're still in it for Grant Williams who visited that weekend.
As I said above, he's not the salesman or the media leaker that Pearl and Tyndall were, and a lot of people won't like that, but just because you don't hear things don't mean he's not out recruiting, or hosting summer camps or coaching clinics.
