Training camp practices don't officially begin until Friday but over the past three days, the Raiders rookies, quarterbacks, and a few select players - many of whom were injured all or most of last season - had their own warm up practices at the Napa training camp facility.
The veteran players have the benefit of having gone through training camp before, and having played all 16 games last season. For some of them training camp is old hat as well as the process in preparing themselves.
In that regard, the three-days of pre-camp practices were vital in getting the rookies up to speed before the veterans arrive, which happens today.
