I was aware of the rookie mini-camp. Most teams have a rookie mini-shortly after the draft to help the rookies get familiar with how things are done in the NFL. Don't expect anything too intense. Just some positional drills, but mostly its a time to get acquainted with the coaching staff & to start learning how to be a pro.
I believe 2 weeks or so after the rookie minicamp they begin minicamps with the full squad. That's when we'll see a little more action, and then after that wraps up the full training camp starts up shortly thereafter. Then it's on to the preseason, and the regular season. Can't wait.
