I can't provide a direct answer to your question but I'm sure someone who's been to camp will post a reply.
Said this, here are some quotes from Rodney himself that appear in a Paul Perillo feature in PFW.
"I went to mini-camp in May and I made a couple of plays. People were complimenting me on how I looked. Tom Brady came up to me and told me that I had my speed back."
"I feel a lot better, a lot more comfortable, a lot more confident. I'm ready to go."
"Physically I'm able to do more things and I have more confidence moving and jumping and cutting. Of course, [training camp last year] was 10 months after I initially got hurt [three torn knee ligaments] so of course over a year-and-a-half later I feel a lot better. I feel pretty good and I just want to keep working on it, keep rehabbing it and come out here and hopefully I can make some plays."
"Eugene, he's worked his butt off and I've worked my butt off and it's time to kind of recapture that feeling we had, that unity we had, back there. I love playing with Eugene. He's a very athletic safety. He communicates well and he's a guy I'm very familiar with. We're healthy now and ready to go."
